/* This is published for the benefit of "friends" marshal.c and _decimal.c. */

/* 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:

- 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.

/* Long integer representation.

Long integers are made up of a number of 30- or 15-bit digits, depending on
   the platform. The number of digits (ndigits) is stored in the high bits of
   the lv_tag field (lvtag >> _PyLong_NON_SIZE_BITS).

The absolute value of a number is equal to
        SUM(for i=0 through ndigits-1) ob_digit[i] * 2**(PyLong_SHIFT*i)

The sign of the value is stored in the lower 2 bits of lv_tag.

- 0: Positive
    - 1: Zero
    - 2: Negative

The third lowest bit of lv_tag is reserved for an immortality flag, but is
   not currently used.

In a normalized number, ob_digit[ndigits-1] (the most significant
   digit) is never zero.  Also, in all cases, for all valid i,
        0 <= ob_digit[i] <= PyLong_MASK.

The allocation function takes care of allocating extra memory
   so that ob_digit[0] ... ob_digit[ndigits-1] are actually available.
   We always allocate memory for at least one digit, so accessing ob_digit[0]
   is always safe. However, in the case ndigits == 0, the contents of
   ob_digit[0] may be undefined.
