PyOS_strtol
C_long PyOS_strtol(char*, char**, int): Availability: 3.*
PyOS_strtoul
C_ulong PyOS_strtoul(char*, char**, int): Availability: 3.*
_PyLong_AsByteArray int _PyLong_AsByteArray(PyLongObject* v, ubyte* bytes, size_t n, int little_endian, int is_signed): Convert the least-significant 8*n bits of long v to a base-256 integer, stored in array bytes. Normally return 0, return -1 on error. If little_endian is 1/true, store the MSB at bytes[n-1] and the LSB at bytes[0]; else (little_endian is 0/false) store the MSB at bytes[0] and the LSB at bytes[n-1]. If is_signed is 0/false, it's an error if v < 0; else (v >= 0) n bytes are filled and there's nothing special about bit 0x80 of the MSB. If is_signed is 1/true, bytes is filled with the 2's-complement representation of v's value. Bit 0x80 of the MSB is the sign bit. Error returns (-1): + is_signed is 0 and v < 0. TypeError is set in this case, and bytes isn't altered. + n isn't big enough to hold the full mathematical value of v. For example, if is_signed is 0 and there are more digits in the v than fit in n; or if is_signed is 1, v < 0, and n is just 1 bit shy of being large enough to hold a sign bit. OverflowError is set in this case, but bytes holds the least-signficant n bytes of the true value.
_PyLong_DivmodNear PyObject* _PyLong_DivmodNear(PyObject*, PyObject*): Availability: 3.*
_PyLong_Format PyObject* _PyLong_Format(PyObject* aa, int base): Availability: 3.*
_PyLong_Format PyObject* _PyLong_Format(PyObject* aa, int base, int addL, int newstyle)
_PyLong_FormatAdvanced PyObject* _PyLong_FormatAdvanced(PyObject* obj, Py_UNICODE* format_spec, Py_ssize_t format_spec_len): Availability: 3.*
_PyLong_FormatAdvanced PyObject* _PyLong_FormatAdvanced(PyObject* obj, char* format_spec, Py_ssize_t format_spec_len): Format the object based on the format_spec, as defined in PEP 3101 (Advanced String Formatting).
_PyLong_Frexp double _PyLong_Frexp(PyLongObject* a, Py_ssize_t* e): _PyLong_Frexp returns a double x and an exponent e such that the true value is approximately equal to x * 2**e. e is >= 0. x is 0.0 if and only if the input is 0 (in which case, e and x are both zeroes); otherwise, 0.5 <= abs(x) < 1.0. On overflow, which is possible if the number of bits doesn't fit into a Py_ssize_t, sets OverflowError and returns -1.0 for x, 0 for e. */ /// Availability: >= 2.
_PyLong_FromByteArray PyObject* _PyLong_FromByteArray(const(ubyte)* bytes, size_t n, int little_endian, int is_signed): View the n unsigned bytes as a binary integer in base 256, and return a Python long with the same numeric value. If n is 0, the integer is 0. Else: If little_endian is 1/true, bytes[n-1] is the MSB and bytes[0] the LSB; else (little_endian is 0/false) bytes[0] is the MSB and bytes[n-1] the LSB. If is_signed is 0/false, view the bytes as a non-negative integer. If is_signed is 1/true, view the bytes as a 2's-complement integer, non-negative if bit 0x80 of the MSB is clear, negative if set. Error returns: + Return NULL with the appropriate exception set if there's not enough memory to create the Python long.
_PyLong_NumBits size_t _PyLong_NumBits(PyObject* v): Return the number of bits needed to represent the absolute value of a long. For example, this returns 1 for 1 and -1, 2 for 2 and -2, and 2 for 3 and -3. It returns 0 for 0. v must not be NULL, and must be a normalized long. (size_t)-1 is returned and OverflowError set if the true result doesn't fit in a size_t.
_PyLong_Sign int _PyLong_Sign(PyObject* v): Return 0 if v is 0, -1 if v < 0, +1 if v > 0. v must not be NULL, and must be a normalized long. There are no error cases.
