Try this..

Math.round(num * 100) / 100

var num = 71.6666666;

a = Math.round(num * 100) / 100

console.log("output :",a);

Math.round(num + "e+2") + "e-2") – prabodhtiwari Feb 22 '17 at 14:13
But your output : 71.67.. I just want 71.66 – Feb 22 '17 at 14:13
Then use Math.trunc(num * 100) / 100, just to trancate – Shivkumar kondi Feb 22 '17 at 14:16
