-/* Parameters of the integer representation. There are two different
- sets of parameters: one set for 30-bit digits, stored in an unsigned 32-bit
- integer type, and one set for 15-bit digits with each digit stored in an
- unsigned short. The value of PYLONG_BITS_IN_DIGIT, defined either at
- configure time or in pyport.h, is used to decide which digit size to use.
-
- Type 'digit' should be able to hold 2*PyLong_BASE-1, and type 'twodigits'
- should be an unsigned integer type able to hold all integers up to
- PyLong_BASE*PyLong_BASE-1. x_sub assumes that 'digit' is an unsigned type,
- and that overflow is handled by taking the result modulo 2**N for some N >
- PyLong_SHIFT. The majority of the code doesn't care about the precise
- value of PyLong_SHIFT, but there are some notable exceptions:
-
- - long_pow() requires that PyLong_SHIFT be divisible by 5
-
- - PyLong_{As,From}ByteArray require that PyLong_SHIFT be at least 8
-
- - long_hash() requires that PyLong_SHIFT is *strictly* less than the number
- of bits in an unsigned long, as do the PyLong <-> long (or unsigned long)
- conversion functions
-
- - the Python int <-> size_t/Py_ssize_t conversion functions expect that
- PyLong_SHIFT is strictly less than the number of bits in a size_t
-
- - the marshal code currently expects that PyLong_SHIFT is a multiple of 15
-
- - NSMALLNEGINTS and NSMALLPOSINTS should be small enough to fit in a single
- digit; with the current values this forces PyLong_SHIFT >= 9
-
- The values 15 and 30 should fit all of the above requirements, on any
- platform.
