| | | | | | (instances of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it easy to maintain the invariant that hash(x) == hash(y) whenever x and y have equal value.

The basic algorithm remains the same; the most significant speedups come from the following three changes: (1) normalize by shifting instead of multiplying and dividing (2) the old algorithm usually did an unnecessary extra iteration of the outer loop; remove this. As a special case, this means that long divisions with a single-digit result run twice as fast as before. (3) make inner loop much tighter. Various benchmarks show speedups of between 50% and 150% for long integer divisions and modulo operations. ........
