Math.floor vs ~~ vs >> 0

Benchmark created on

Description

Integer division

Setup

const floor = (num, den) => {
	return Math.floor(num / den);
};
const tilde = (num, den) => {
	return ~~(num / den);
};
const gtgtz = (num, den) => {
	return (num / den) >> 0;
};
const pipez = (num, den) => {
	return (num / den|0);
};
const remin = (num, den) => {
	return (num - (num % den))/ den;
};
