javascript. How to nicely format floating numbers to string without unnecessary decimal 0?

Here's an example input:

How do you currently *format* ? You should not have any 0 unless you add them. — Denys Séguret, Oct 27 '14 at 14:38
What *exactly* are you trying to do here? Round to 3 d.p. but only display those d.p. if they are non-zero? If the input was `12.3545` what would you expect the output to be? Are you inputs really numbers? Or are they strings? — Matt Burland, Oct 27 '14 at 14:50

Use parseFloat - it will take care of any floating 0

alert(parseFloat("12.00")); //12
