chop unused decimals with javascript

Question

I\'ve got a currency input and need to return only significant digits. The input always has two decimal places, so:

4.00  ->  4
4.10  ->  4.1
4.01  ->           


        

Answer 1

I believe parseFloat() does this.

parseFloat(4.00) // 4
parseFloat(4.10) // 4.1
parseFloat(4.01) // 4.01
