| /* 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. | ||||
