23 * Arbitrary-precision integer arithmetic. *
24 * For speed, we work in groups of bits, even though this *
25 * complicates algorithms. *
26 * Each group of bits is called a 'littlenum'. *
27 * A bunch of littlenums representing a (possibly large) *
28 * integer is called a 'bignum'. *
29 * Bignums are >= 0. *
