shuax / fast_pow10_division.md
Created August 31, 2023 02:31 — forked from loicmolinari/fast_pow10_division.md
Fast power-of-10 division using multiply and shift magic constants in a look-up table instead of a costly division operation.

DivPow10(U64 a, S64 index)
{
    ASSERT(index >= 0 && index < 19);
