A fast alternative to the modulo reduction – Daniel Lemire

WebJun 27, 2016 · It is a fair map with a bias for smaller values. It works, but a modulo reduction involves a division, and divisions are expensive. Much more expensive than multiplications. A single 32-bit division on a recent x64 processor has a throughput of one instruction every six cycles with a latency of 26 cycles. WebModulo Operation. The modulo (or "modulus" or "mod") is the remainder after dividing one number by another. Example: 100 mod 9 equals 1. Because 1009 = 11 with a remainder of 1. ... 14 mod 12 = 2. Some programming languages use the percent sign: 14 % 12 = 2, but % is just a convenient symbol and has nothing to do with percents. deep bodied food fish
