parseInt
var decimal = 30.0; for (var i = 0; i < 10000; i++) { decimal += (i / 1000); el.innerHTML = parseInt(decimal, 10); }
toFixed
var decimal = 30.0; for (var i = 0; i < 10000; i++) { decimal += (i / 1000); el.innerHTML = decimal.toFixed(); }
Tilde
var decimal = 30.0; for (var i = 0; i < 10000; i++) { decimal += (i / 1000); el.innerHTML = ~~decimal; }
Bitwise
var decimal = 30.0; for (var i = 0; i < 10000; i++) { decimal += (i / 1000); el.innerHTML = decimal | 0; }
Math.round
var decimal = 30.0; for (var i = 0; i < 10000; i++) { decimal += (i / 1000); el.innerHTML = Math.round(decimal); }
Math.trunc
var decimal = 30.0; for (var i = 0; i < 10000; i++) { decimal += (i / 1000); el.innerHTML = Math.trunc(decimal); }
