I am stuck in problem with JavaScript calculation. as below code shows;

$(function(){   
        console.log(17.8575 + 142.86); // actual 160.71750000000003 and expected 160.7175 
        console.log(47.62*3); // actual 142.85999999999999 and excepted 142.86
    });

and I dont want to use toFixed() function. How to come over this problem? Thanks in advance.

Any good reason not to use `toFixed`? – Andrey Sep 07 '15 at 14:30
That's how floating point math works. One possibility is to switch to integer math. – Raymond Chen Sep 07 '15 at 14:31
because I am working with money, where 47.62 is Rate and 3 is Qty and want to calculate exact amount as 142.86. – iTechOwl Sep 07 '15 at 14:32
