Rounding numbers to 2 digits after comma

Question

I have no idea how to do this? I\'m adding comma numbers, result is of course always a number with way too many digits after the comma. anyone?

Answer 1

This worked for me:

var new_number = float.toFixed(2);

Example:

var my_float = 0.6666

my_float.toFixed(3) # => 0.667
