How to format float number in standered javascript

Question

My number float number is 0.23343

In rails sprintf("%05.2f", size_kwh_minutes) its give me 00.23 In javascript i am using size_kwh_minutes.toFixed(2) its give me 0.23

How can i do format 00.23 in javascript.

I don't think `00.23` is a valid `number`. You could always make it a string — Johan, Feb 19 '14 at 12:56

    return Math.round(num * Math.pow(10, decimals)) / Math.pow(10, decimals);
}

preciseRound(yourNumber, 2);
