Rounding problems with calculate numbers in Javascript

Question

I've got the following problem when i'm counting in javascript.

var processAmount = parseFloat(166.98) - parseFloat(61.58);

The result is: 105.39999999999999

Doesnt matter if I use parseFloat() or not.

How can I solve this?

solve what? We can only assume what expected output is since you haven't defined it — charlietfl, Oct 06 '14 at 13:02
Yes `.toFixed(2)` works fine in this case. `var processAmount = parseFloat(parseFloat(166.98).toFixed(2) - parseFloat(61.58).toFixed(2)).toFixed(2);` — Deepak Biswal, Oct 06 '14 at 13:08

Sometimes floats numbers cannot be represented exactly in binary.

Try this:

var processAmount = parseFloat(166.98) - parseFloat(61.58);
processAmount.toFixed(2);
