msgid "Integer Objects"
msgid "All integers are implemented as \"long\" integer objects of arbitrary size."
msgid "On error, most ``PyLong_As*`` APIs return ``(return type)-1`` which cannot be distinguished from a number.  Use :c:func:`PyErr_Occurred` to disambiguate."
msgid "This subtype of :c:type:`PyObject` represents a Python integer object."
msgid "This instance of :c:type:`PyTypeObject` represents the Python integer type. This is the same object as :class:`int` in the Python layer."
msgid "Return true if its argument is a :c:type:`PyLongObject` or a subtype of :c:type:`PyLongObject`.  This function always succeeds."
msgid "Return true if its argument is a :c:type:`PyLongObject`, but not a subtype of :c:type:`PyLongObject`.  This function always succeeds."
msgid "Return a new :c:type:`PyLongObject` object from *v*, or ``NULL`` on failure."
msgid "CPython keeps an array of integer objects for all integers between ``-5`` and ``256``.  When you create an int in that range you actually just get back a reference to the existing object."
msgid "Return a new :c:type:`PyLongObject` object from a C :c:expr:`unsigned long`, or ``NULL`` on failure."
msgid "Return a new :c:type:`PyLongObject` object from a C :c:type:`Py_ssize_t`, or ``NULL`` on failure."
msgid "Return a new :c:type:`PyLongObject` object from a C :c:type:`size_t`, or ``NULL`` on failure."
msgid "Return a new :c:type:`PyLongObject` object from a C :c:expr:`long long`, or ``NULL`` on failure."
msgid "Return a new :c:type:`PyLongObject` object from a C :c:expr:`unsigned long long`, or ``NULL`` on failure."
msgid "Return a new :c:type:`PyLongObject` object from a signed C :c:expr:`int32_t` or :c:expr:`int64_t`, or ``NULL`` with an exception set on failure."
msgid "Return a new :c:type:`PyLongObject` object from an unsigned C :c:expr:`uint32_t` or :c:expr:`uint64_t`, or ``NULL`` with an exception set on failure."
msgid "Return a new :c:type:`PyLongObject` object from the integer part of *v*, or ``NULL`` on failure."
msgid "Return a new :c:type:`PyLongObject` based on the string value in *str*, which is interpreted according to the radix in *base*, or ``NULL`` on failure.  If *pend* is non-``NULL``, *\\*pend* will point to the end of *str* on success or to the first character that could not be processed on error.  If *base* is ``0``, *str* is interpreted using the :ref:`integers` definition; in this case, leading zeros in a non-zero decimal number raises a :exc:`ValueError`.  If *base* is not ``0``, it must be between ``2`` and ``36``, inclusive.  Leading and trailing whitespace and single underscores after a base specifier and between digits are ignored.  If there are no digits or *str* is not NULL-terminated following the digits and trailing whitespace, :exc:`ValueError` will be raised."
msgid ":c:func:`PyLong_AsNativeBytes()` and :c:func:`PyLong_FromNativeBytes()` functions can be used to convert a :c:type:`PyLongObject` to/from an array of bytes in base ``256``."
msgid "Convert a sequence of Unicode digits in the string *u* to a Python integer value."
msgid "Create a Python integer from the pointer *p*. The pointer value can be retrieved from the resulting value using :c:func:`PyLong_AsVoidPtr`."
msgid "Create a Python integer from the value contained in the first *n_bytes* of *buffer*, interpreted as a two's-complement signed number."
msgid "*flags* are as for :c:func:`PyLong_AsNativeBytes`. Passing ``-1`` will select the native endian that CPython was compiled with and assume that the most-significant bit is a sign bit. Passing ``Py_ASNATIVEBYTES_UNSIGNED_BUFFER`` will produce the same result as calling :c:func:`PyLong_FromUnsignedNativeBytes`. Other flags are ignored."
msgid "Create a Python integer from the value contained in the first *n_bytes* of *buffer*, interpreted as an unsigned number."
msgid "*flags* are as for :c:func:`PyLong_AsNativeBytes`. Passing ``-1`` will select the native endian that CPython was compiled with and assume that the most-significant bit is not a sign bit. Flags other than endian are ignored."
msgid "Macro for creating a Python integer from a process identifier."
msgid "This can be defined as an alias to :c:func:`PyLong_FromLong` or :c:func:`PyLong_FromLongLong`, depending on the size of the system's PID type."
msgid "Return a C :c:expr:`long` representation of *obj*.  If *obj* is not an instance of :c:type:`PyLongObject`, first call its :meth:`~object.__index__` method (if present) to convert it to a :c:type:`PyLongObject`."
msgid "Raise :exc:`OverflowError` if the value of *obj* is out of range for a :c:expr:`long`."
msgid "Returns ``-1`` on error.  Use :c:func:`PyErr_Occurred` to disambiguate."
msgid "Use :meth:`~object.__index__` if available."
msgid "This function will no longer use :meth:`~object.__int__`."
msgid "Exactly equivalent to the preferred ``PyLong_AsLong``. In particular, it can fail with :exc:`OverflowError` or another exception."
msgid "Similar to :c:func:`PyLong_AsLong`, but store the result in a C :c:expr:`int` instead of a C :c:expr:`long`."
msgid "If the value of *obj* is greater than :c:macro:`LONG_MAX` or less than :c:macro:`LONG_MIN`, set *\\*overflow* to ``1`` or ``-1``, respectively, and return ``-1``; otherwise, set *\\*overflow* to ``0``.  If any other exception occurs set *\\*overflow* to ``0`` and return ``-1`` as usual."
msgid "Return a C :c:expr:`long long` representation of *obj*.  If *obj* is not an instance of :c:type:`PyLongObject`, first call its :meth:`~object.__index__` method (if present) to convert it to a :c:type:`PyLongObject`."
msgid "Raise :exc:`OverflowError` if the value of *obj* is out of range for a :c:expr:`long long`."
msgid "If the value of *obj* is greater than :c:macro:`LLONG_MAX` or less than :c:macro:`LLONG_MIN`, set *\\*overflow* to ``1`` or ``-1``, respectively, and return ``-1``; otherwise, set *\\*overflow* to ``0``.  If any other exception occurs set *\\*overflow* to ``0`` and return ``-1`` as usual."

msgid "Raise :exc:`OverflowError` if the value of *pylong* is out of range for a :c:expr:`unsigned long`."
msgid "Returns ``(unsigned long)-1`` on error. Use :c:func:`PyErr_Occurred` to disambiguate."
msgid "Return a C :c:type:`size_t` representation of *pylong*.  *pylong* must be an instance of :c:type:`PyLongObject`."
msgid "Raise :exc:`OverflowError` if the value of *pylong* is out of range for a :c:type:`size_t`."
msgid "Returns ``(size_t)-1`` on error. Use :c:func:`PyErr_Occurred` to disambiguate."

msgid "Raise :exc:`OverflowError` if the value of *pylong* is out of range for an :c:expr:`unsigned long long`."
msgid "Returns ``(unsigned long long)-1`` on error. Use :c:func:`PyErr_Occurred` to disambiguate."
msgid "A negative *pylong* now raises :exc:`OverflowError`, not :exc:`TypeError`."
msgid "Return a C :c:expr:`unsigned long` representation of *obj*.  If *obj* is not an instance of :c:type:`PyLongObject`, first call its :meth:`~object.__index__` method (if present) to convert it to a :c:type:`PyLongObject`."
msgid "If the value of *obj* is out of range for an :c:expr:`unsigned long`, return the reduction of that value modulo ``ULONG_MAX + 1``."
msgid "Returns ``(unsigned long)-1`` on error.  Use :c:func:`PyErr_Occurred` to disambiguate."
msgid "Return a C :c:expr:`unsigned long long` representation of *obj*.  If *obj* is not an instance of :c:type:`PyLongObject`, first call its :meth:`~object.__index__` method (if present) to convert it to a :c:type:`PyLongObject`."
msgid "If the value of *obj* is out of range for an :c:expr:`unsigned long long`, return the reduction of that value modulo ``ULLONG_MAX + 1``."
msgid "Returns ``(unsigned long long)-1`` on error.  Use :c:func:`PyErr_Occurred` to disambiguate."
msgid "Set *\\*value* to a signed C :c:expr:`int32_t` or :c:expr:`int64_t` representation of *obj*."
msgid "If *obj* is not an instance of :c:type:`PyLongObject`, first call its :meth:`~object.__index__` method (if present) to convert it to a :c:type:`PyLongObject`."
msgid "If the *obj* value is out of range, raise an :exc:`OverflowError`."
msgid "Set *\\*value* and return ``0`` on success. Set an exception and return ``-1`` on error."
msgid "*value* must not be ``NULL``."
msgid "Set *\\*value* to an unsigned C :c:expr:`uint32_t` or :c:expr:`uint64_t` representation of *obj*."
msgid "If *obj* is negative, raise a :exc:`ValueError`."
msgid "Return a C :c:expr:`double` representation of *pylong*.  *pylong* must be an instance of :c:type:`PyLongObject`."
msgid "Raise :exc:`OverflowError` if the value of *pylong* is out of range for a :c:expr:`double`."
msgid "Returns ``-1.0`` on error.  Use :c:func:`PyErr_Occurred` to disambiguate."
msgid "Convert a Python integer *pylong* to a C :c:expr:`void` pointer. If *pylong* cannot be converted, an :exc:`OverflowError` will be raised.  This is only assured to produce a usable :c:expr:`void` pointer for values created with :c:func:`PyLong_FromVoidPtr`."
msgid "Returns ``NULL`` on error.  Use :c:func:`PyErr_Occurred` to disambiguate."
msgid "Copy the Python integer value *pylong* to a native *buffer* of size *n_bytes*. The *flags* can be set to ``-1`` to behave similarly to a C cast, or to values documented below to control the behavior."
msgid "Returns ``-1`` with an exception raised on error.  This may happen if *pylong* cannot be interpreted as an integer, or if *pylong* was negative and the ``Py_ASNATIVEBYTES_REJECT_NEGATIVE`` flag was set."
msgid "Otherwise, returns the number of bytes required to store the value. If this is equal to or less than *n_bytes*, the entire value was copied. All *n_bytes* of the buffer are written: remaining bytes filled by copies of the sign bit."
msgid "If the returned value is greater than *n_bytes*, the value was truncated: as many of the lowest bits of the value as could fit are written, and the higher bits are ignored. This matches the typical behavior of a C-style downcast."
msgid "Overflow is not considered an error. If the returned value is larger than *n_bytes*, most significant bits were discarded."
msgid "``0`` will never be returned."
msgid "Values are always copied as two's-complement."
msgid "Usage example::"
"int32_t value;\n"
"Py_ssize_t bytes = PyLong_AsNativeBytes(pylong, &value, sizeof(value), -1);\n"
"if (bytes < 0) {\n"
"    // Failed. A Python exception was set with the reason.\n"
"    return NULL;\n"
"else if (bytes <= (Py_ssize_t)sizeof(value)) {\n"
"    // Success!\n"
"    // Overflow occurred, but 'value' contains the truncated\n"
"    // lowest bits of pylong.\n"
msgid "Passing zero to *n_bytes* will return the size of a buffer that would be large enough to hold the value. This may be larger than technically necessary, but not unreasonably so. If *n_bytes=0*, *buffer* may be ``NULL``."
msgid "Passing *n_bytes=0* to this function is not an accurate way to determine the bit length of the value."
msgid "To get at the entire Python value of an unknown size, the function can be called twice: first to determine the buffer size, then to fill it::"
"// Ask how much space we need.\n"
"Py_ssize_t expected = PyLong_AsNativeBytes(pylong, NULL, 0, -1);\n"
"if (expected < 0) {\n"
"    // Failed. A Python exception was set with the reason.\n"
"    return NULL;\n"
"assert(expected != 0);  // Impossible per the API definition.\n"
"uint8_t *bignum = malloc(expected);\n"
"if (!bignum) {\n"
"    PyErr_SetString(PyExc_MemoryError, \"bignum malloc failed.\");\n"
"    return NULL;\n"
"// Safely get the entire value.\n"
"Py_ssize_t bytes = PyLong_AsNativeBytes(pylong, bignum, expected, -1);\n"
"if (bytes < 0) {  // Exception has been set.\n"
"    free(bignum);\n"
"    return NULL;\n"
"else if (bytes > expected) {  // This should not be possible.\n"
"    PyErr_SetString(PyExc_RuntimeError,\n"
"        \"Unexpected bignum truncation after a size check.\");\n"
"    free(bignum);\n"
"    return NULL;\n"
"// The expected success given the above pre-check.\n"
"// ... use bignum ...\n"
"free(bignum);"
msgid "*flags* is either ``-1`` (``Py_ASNATIVEBYTES_DEFAULTS``) to select defaults that behave most like a C cast, or a combination of the other flags in the table below. Note that ``-1`` cannot be combined with other flags."
msgid "Currently, ``-1`` corresponds to ``Py_ASNATIVEBYTES_NATIVE_ENDIAN | Py_ASNATIVEBYTES_UNSIGNED_BUFFER``."
msgid "Flag"
msgid "Value"
msgid "``-1``"
msgid "``0``"
msgid "``1``"
msgid "``3``"
msgid "``4``"
msgid "``8``"
msgid "``16``"
msgid "Specifying ``Py_ASNATIVEBYTES_NATIVE_ENDIAN`` will override any other endian flags. Passing ``2`` is reserved."
msgid "By default, sufficient buffer will be requested to include a sign bit. For example, when converting 128 with *n_bytes=1*, the function will return 2 (or more) in order to store a zero sign bit."
msgid "If ``Py_ASNATIVEBYTES_UNSIGNED_BUFFER`` is specified, a zero sign bit will be omitted from size calculations. This allows, for example, 128 to fit in a single-byte buffer. If the destination buffer is later treated as signed, a positive input value may become negative. Note that the flag does not affect handling of negative values: for those, space for a sign bit is always requested."
msgid "Specifying ``Py_ASNATIVEBYTES_REJECT_NEGATIVE`` causes an exception to be set if *pylong* is negative. Without this flag, negative values will be copied provided there is enough space for at least one sign bit, regardless of whether ``Py_ASNATIVEBYTES_UNSIGNED_BUFFER`` was specified."
msgid "If ``Py_ASNATIVEBYTES_ALLOW_INDEX`` is specified and a non-integer value is passed, its :meth:`~object.__index__` method will be called first. This may result in Python code executing and other threads being allowed to run, which could cause changes to other objects or values in use. When *flags* is ``-1``, this option is not set, and non-integer values will raise :exc:`TypeError`."
msgid "With the default *flags* (``-1``, or *UNSIGNED_BUFFER*  without *REJECT_NEGATIVE*), multiple Python integers can map to a single value without overflow. For example, both ``255`` and ``-1`` fit a single-byte buffer and set all its bits. This matches typical C cast behavior."
msgid "Macro for converting a Python integer into a process identifier."
msgid "This can be defined as an alias to :c:func:`PyLong_AsLong`, :c:func:`PyLong_FromLongLong`, or :c:func:`PyLong_AsInt`, depending on the size of the system's PID type."
msgid "Get the sign of the integer object *obj*."
msgid "On success, set *\\*sign* to the integer sign  (0, -1 or +1 for zero, negative or positive integer, respectively) and return 0."
msgid "On failure, return -1 with an exception set.  This function always succeeds if *obj* is a :c:type:`PyLongObject` or its subtype."
msgid "Check if the integer object *obj* is positive (``obj > 0``)."
msgid "If *obj* is an instance of :c:type:`PyLongObject` or its subtype, return ``1`` when it's positive and ``0`` otherwise.  Else set an exception and return ``-1``."
msgid "Check if the integer object *obj* is negative (``obj < 0``)."
msgid "If *obj* is an instance of :c:type:`PyLongObject` or its subtype, return ``1`` when it's negative and ``0`` otherwise.  Else set an exception and return ``-1``."
msgid "Check if the integer object *obj* is zero."
msgid "If *obj* is an instance of :c:type:`PyLongObject` or its subtype, return ``1`` when it's zero and ``0`` otherwise.  Else set an exception and return ``-1``."
msgid "On success, return a read only :term:`named tuple`, that holds information about Python's internal representation of integers. See :data:`sys.int_info` for description of individual fields."
msgid "On failure, return ``NULL`` with an exception set."
msgid "Return 1 if *op* is compact, 0 otherwise."
msgid "This function makes it possible for performance-critical code to implement a “fast path” for small integers. For compact values use :c:func:`PyUnstable_Long_CompactValue`; for others fall back to a :c:func:`PyLong_As* <PyLong_AsSize_t>` function or :c:func:`PyLong_AsNativeBytes`."
msgid "The speedup is expected to be negligible for most users."
msgid "Exactly what values are considered compact is an implementation detail and is subject to change."
msgid "If *op* is compact, as determined by :c:func:`PyUnstable_Long_IsCompact`, return its value."
msgid "Otherwise, the return value is undefined."
msgid "Export API"
msgid "Layout of an array of \"digits\" (\"limbs\" in the GMP terminology), used to represent absolute value for arbitrary precision integers."
msgid "Use :c:func:`PyLong_GetNativeLayout` to get the native layout of Python :class:`int` objects, used internally for integers with \"big enough\" absolute value."
msgid "See also :data:`sys.int_info` which exposes similar information in Python."
msgid "Bits per digit. For example, a 15 bit digit means that bits 0-14 contain meaningful information."
msgid "Digit size in bytes. For example, a 15 bit digit will require at least 2 bytes."
msgid "Digits order:"
msgid "``1`` for most significant digit first"
msgid "``-1`` for least significant digit first"
msgid "Digit endianness:"
msgid "``1`` for most significant byte first (big endian)"
msgid "``-1`` for least significant byte first (little endian)"
msgid "Get the native layout of Python :class:`int` objects."
msgid "See the :c:struct:`PyLongLayout` structure."
msgid "The function must not be called before Python initialization nor after Python finalization. The returned layout is valid until Python is finalized. The layout is the same for all Python sub-interpreters in a process, and so it can be cached."
msgid "Export of a Python :class:`int` object."
msgid "There are two cases:"
msgid "If :c:member:`digits` is ``NULL``, only use the :c:member:`value` member."
msgid "If :c:member:`digits` is not ``NULL``, use :c:member:`negative`, :c:member:`ndigits` and :c:member:`digits` members."
msgid "The native integer value of the exported :class:`int` object. Only valid if :c:member:`digits` is ``NULL``."
msgid "``1`` if the number is negative, ``0`` otherwise. Only valid if :c:member:`digits` is not ``NULL``."
msgid "Number of digits in :c:member:`digits` array. Only valid if :c:member:`digits` is not ``NULL``."
msgid "Read-only array of unsigned digits. Can be ``NULL``."
msgid "Export a Python :class:`int` object."
msgid "*export_long* must point to a :c:struct:`PyLongExport` structure allocated by the caller. It must not be ``NULL``."
msgid "On success, fill in *\\*export_long* and return ``0``. On error, set an exception and return ``-1``."
msgid ":c:func:`PyLong_FreeExport` must be called when the export is no longer needed."
msgid "This function always succeeds if *obj* is a Python :class:`int` object or a subclass."
msgid "Release the export *export_long* created by :c:func:`PyLong_Export`."
msgid "Calling :c:func:`PyLong_FreeExport` is optional if *export_long->digits* is ``NULL``."
msgid "PyLongWriter API"
msgid "The :c:type:`PyLongWriter` API can be used to import an integer."
msgid "A Python :class:`int` writer instance."
msgid "The instance must be destroyed by :c:func:`PyLongWriter_Finish` or :c:func:`PyLongWriter_Discard`."
msgid "Create a :c:type:`PyLongWriter`."
msgid "On success, allocate *\\*digits* and return a writer. On error, set an exception and return ``NULL``."
msgid "*negative* is ``1`` if the number is negative, or ``0`` otherwise."
msgid "*ndigits* is the number of digits in the *digits* array. It must be greater than 0."
msgid "*digits* must not be NULL."
msgid "After a successful call to this function, the caller should fill in the array of digits *digits* and then call :c:func:`PyLongWriter_Finish` to get a Python :class:`int`. The layout of *digits* is described by :c:func:`PyLong_GetNativeLayout`."
msgid "Digits must be in the range [``0``; ``(1 << bits_per_digit) - 1``] (where the :c:struct:`~PyLongLayout.bits_per_digit` is the number of bits per digit). Any unused most significant digits must be set to ``0``."
msgid "Alternately, call :c:func:`PyLongWriter_Discard` to destroy the writer instance without creating an :class:`~int` object."
msgid "Finish a :c:type:`PyLongWriter` created by :c:func:`PyLongWriter_Create`."
msgid "On success, return a Python :class:`int` object. On error, set an exception and return ``NULL``."
msgid "The function takes care of normalizing the digits and converts the object to a compact integer if needed."
msgid "The writer instance and the *digits* array are invalid after the call."
msgid "Discard a :c:type:`PyLongWriter` created by :c:func:`PyLongWriter_Create`."
msgid "If *writer* is ``NULL``, no operation is performed."
msgid "Deprecated API"
msgid "These macros are :term:`soft deprecated`. They describe parameters of the internal representation of :c:type:`PyLongObject` instances."
msgid "Use :c:func:`PyLong_GetNativeLayout` instead, along with :c:func:`PyLong_Export` to read integer data or :c:type:`PyLongWriter` to write it. These currently use the same layout, but are designed to continue working correctly even if CPython's internal integer representation changes."
msgid "This is equivalent to :c:member:`~PyLongLayout.bits_per_digit` in the output of :c:func:`PyLong_GetNativeLayout`."
msgid "This is currently equivalent to :c:expr:`1 << PyLong_SHIFT`."
msgid "This is currently equivalent to :c:expr:`(1 << PyLong_SHIFT) - 1`"
