Javascript: Addition of Floating numbers gives incorrect precision

Question

I add this floating numbers in javascript,
1403.07+1000.00 result is 2403.0699999999997

It should be 2403.07

I got a work around (1403.07+1000.00).toFixed(2), but this will fail if precision changes meaning; it will fail for addition of 1403.072+1000.01.

Is there any way I can achieve by jQuery/Javascipt, i dont need external library.

var result = 2403.0699999999997;
result =   result.toFixed(2); //returns string fixed to 2 decimal places
result =   parseFloat(result);//returns double 2 decimal places
alert(result);

using .toFixed(2) will be limited to 2 precisions. for 1403.072+1000.01, result should be ** 2403.082 ** . whereas, with .toFixed(2), would only give ** 2403.08 ** . – user5767237 Dec 05 '16 at 06:41
