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 think this is what you want

    v = 33.404034
    v.toFixed(2) # v -> 33.40
    parseFloat(v.toFixed(2)) # 33.4

and you have

    v = 33.00704034
    v.toFixed(2) # v -> 33.01
    parseFloat(v.toFixed(2)) # 33.01

    v = 33.00304034
    v.toFixed(2) # v -> 33.00
    parseFloat(v.toFixed(2)) # 33
