How to parse float with two decimal places in javascript?

Question

I have the following code. I would like to have it such that if price_result equals an integer, let\'s say 10, then I would like to add two decimal places. So 10 would be 10

Answer 1

If you need performance (like in games):

Math.round(number * 100) / 100

It's about 100 times as fast as parseFloat(number.toFixed(2))
