Benchmark: Round Numbers to 2 digits

Script Preparation code:

var number = 12324242/432432432;
var result;

function round(value, decimals) {
    value = value * Math.pow(10, decimals);
    value = Math.round(value);
    value = value / Math.pow(10, decimals);
    return value;
}

Tests:

toFixed
result = +(number.toFixed(2));
Math.round
result = Math.round((100 - (number) * 100) * 100) / 100;
Round function with correction
result = round(number, 2);
