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 am trying to find a solution like that right now. This is how I got here.

I used Number() function for my application, but looks like it's working the same as parseFloat()

I remove and commas before checking the number.

 var valueAsNumber = Number( val.replace(/\,/g,'') );
