Long Integer Objects¶
- 
PyTypeObject PyLong_Type¶
- This instance of - PyTypeObjectrepresents the Python long integer type. This is the same object as- longand- types.LongType.
- 
int PyLong_Check(PyObject *p)¶
- Return true if its argument is a - PyLongObjector a subtype of- PyLongObject.- Changed in version 2.2: Allowed subtypes to be accepted. 
- 
int PyLong_CheckExact(PyObject *p)¶
- Return true if its argument is a - PyLongObject, but not a subtype of- PyLongObject.- New in version 2.2. 
- 
PyObject* PyLong_FromLong(long v)¶
- Return value: New reference.Return a new PyLongObjectobject from v, or NULL on failure.
- 
PyObject* PyLong_FromUnsignedLong(unsigned long v)¶
- Return value: New reference.Return a new PyLongObjectobject from a Cunsigned long, or NULL on failure.
- 
PyObject* PyLong_FromSsize_t(Py_ssize_t v)¶
- Return value: New reference.Return a new PyLongObjectobject from a CPy_ssize_t, or NULL on failure.New in version 2.6. 
- 
PyObject* PyLong_FromSize_t(size_t v)¶
- Return value: New reference.Return a new PyLongObjectobject from a Csize_t, or NULL on failure.New in version 2.6. 
- 
PyObject* PyLong_FromLongLong(PY_LONG_LONG v)¶
- Return value: New reference.Return a new PyLongObjectobject from a Clong long, or NULL on failure.
- 
PyObject* PyLong_FromUnsignedLongLong(unsigned PY_LONG_LONG v)¶
- Return value: New reference.Return a new PyLongObjectobject from a Cunsigned long long, or NULL on failure.
- 
PyObject* PyLong_FromDouble(double v)¶
- Return value: New reference.Return a new PyLongObjectobject from the integer part of v, or NULL on failure.
- 
PyObject* PyLong_FromString(char *str, char **pend, int base)¶
- Return value: New reference.Return a new PyLongObjectbased on the string value in str, which is interpreted according to the radix in base. If pend is non-NULL, *pend will point to the first character in str which follows the representation of the number. If base is0, the radix will be determined based on the leading characters of str: if str starts with'0x'or'0X', radix 16 will be used; if str starts with'0', radix 8 will be used; otherwise radix 10 will be used. If base is not0, it must be between2and36, inclusive. Leading spaces are ignored. If there are no digits,ValueErrorwill be raised.
- 
PyObject* PyLong_FromUnicode(Py_UNICODE *u, Py_ssize_t length, int base)¶
- Return value: New reference.Convert a sequence of Unicode digits to a Python long integer value. The first parameter, u, points to the first character of the Unicode string, length gives the number of characters, and base is the radix for the conversion. The radix must be in the range [2, 36]; if it is out of range, ValueErrorwill be raised.New in version 1.6. Changed in version 2.5: This function used an intfor length. This might require changes in your code for properly supporting 64-bit systems.
- 
PyObject* PyLong_FromVoidPtr(void *p)¶
- Return value: New reference.Create a Python integer or long integer from the pointer p. The pointer value can be retrieved from the resulting value using PyLong_AsVoidPtr().New in version 1.5.2. Changed in version 2.5: If the integer is larger than LONG_MAX, a positive long integer is returned. 
- 
long PyLong_AsLong(PyObject *pylong)¶
- Return a C - longrepresentation of the contents of pylong. If pylong is greater than- LONG_MAX, an- OverflowErroris raised and- -1will be returned.
- 
long PyLong_AsLongAndOverflow(PyObject *pylong, int *overflow)¶
- Return a C - longrepresentation of the contents of pylong. If pylong is greater than- LONG_MAXor less than- LONG_MIN, set *overflow to- 1or- -1, respectively, and return- -1; otherwise, set *overflow to- 0. If any other exception occurs (for example a TypeError or MemoryError), then- -1will be returned and *overflow will be- 0.- New in version 2.7. 
- 
PY_LONG_LONG PyLong_AsLongLongAndOverflow(PyObject *pylong, int *overflow)¶
- Return a C - long longrepresentation of the contents of pylong. If pylong is greater than- PY_LLONG_MAXor less than- PY_LLONG_MIN, set *overflow to- 1or- -1, respectively, and return- -1; otherwise, set *overflow to- 0. If any other exception occurs (for example a TypeError or MemoryError), then- -1will be returned and *overflow will be- 0.- New in version 2.7. 
- 
Py_ssize_t PyLong_AsSsize_t(PyObject *pylong)¶
- Return a C - Py_ssize_trepresentation of the contents of pylong. If pylong is greater than- PY_SSIZE_T_MAX, an- OverflowErroris raised and- -1will be returned.- New in version 2.6. 
- 
unsigned long PyLong_AsUnsignedLong(PyObject *pylong)¶
- Return a C - unsigned longrepresentation of the contents of pylong. If pylong is greater than- ULONG_MAX, an- OverflowErroris raised.
- 
PY_LONG_LONG PyLong_AsLongLong(PyObject *pylong)¶
- Return a C - long longfrom a Python long integer. If pylong cannot be represented as a- long long, an- OverflowErroris raised and- -1is returned.- New in version 2.2. 
- 
unsigned PY_LONG_LONG PyLong_AsUnsignedLongLong(PyObject *pylong)¶
- Return a C - unsigned long longfrom a Python long integer. If pylong cannot be represented as an- unsigned long long, an- OverflowErroris raised and- (unsigned long long)-1is returned.- New in version 2.2. - Changed in version 2.7: A negative pylong now raises - OverflowError, not- TypeError.
- 
unsigned long PyLong_AsUnsignedLongMask(PyObject *io)¶
- Return a C - unsigned longfrom a Python long integer, without checking for overflow.- Returns - (unsigned long)-1on error. Use- PyErr_Occurred()to disambiguate.- New in version 2.3. 
- 
unsigned PY_LONG_LONG PyLong_AsUnsignedLongLongMask(PyObject *io)¶
- Return a C - unsigned long longfrom a Python long integer, without checking for overflow.- Returns - (unsigned PY_LONG_LONG)-1on error. Use- PyErr_Occurred()to disambiguate.- New in version 2.3. 
- 
double PyLong_AsDouble(PyObject *pylong)¶
- Return a C - doublerepresentation of the contents of pylong. If pylong cannot be approximately represented as a- double, an- OverflowErrorexception is raised and- -1.0will be returned.
- 
void* PyLong_AsVoidPtr(PyObject *pylong)¶
- Convert a Python integer or long integer pylong to a C - voidpointer. If pylong cannot be converted, an- OverflowErrorwill be raised. This is only assured to produce a usable- voidpointer for values created with- PyLong_FromVoidPtr().- New in version 1.5.2. - Changed in version 2.5: For values outside 0..LONG_MAX, both signed and unsigned integers are accepted.
