Adding 2 numbers in javascript

Question

While adding 2 numbers I am getting a lengthy decimal part

Pasting the code below.

Number(200.59) + Number(100) = 300.59000000000003 //Expected result 300.59

that's how floating points will work , use `toFixed()` method — Ramanlfc, Feb 29 '16 at 13:31

You could round the number to keep only 2 decimals:

var input = 300.59000000000003
var result = (Math.round(input*100)/100);
alert(result);

Vijay , You are rounding it . But I need to round only if this scenario occurs. – Kapil gopinath Feb 29 '16 at 13:44
