javascript round decimals till two

Question

Working on a form where I am doing a minus from two forms and showing the result in the third one. The problem is when I am for example doing: 0,79 - 0,43 the result becomes: 0,36000000000000004.

So wondering if it's possible to round it to two decimals ?

toFixed does that

output.val(value.toFixed(2).replace('.', ','));

Try this:

Use Math.round(num * 100) / 100
