while vs floor

Benchmark created on

Description

comparing a while loop and floor based flooring for numbers

Setup

function floorImp(M) {
    return M - Math.floor(M);
}


function whileImp(M) {
    while (M > 1) {
        M -= 1;
    }
    while (M < 0) {
        M += 1;
    }
  return M
}

const getRand = () => Math.random() * 2 -1
