Question

I am trying to round to two decimal places in my code below, however, in many cases the Math Round method to control the number of decimal places does not work for me.

   var newKitAmount = 1;
   var priceNumber =  168;
   var updatedTotal = Math.round(priceNumber * newKitAmount*100)/100;
   alert("total is : " + updatedTotal); //OUTPUTS 168 instead of 168.00

Output generated:168

Desired output:168.00

Example two:5 * 2 = 10

Desired output:10.00

JS Fiddle

What am I doing wrong? How can I fix it?

Answer 1

You should use toFixed if you want to get a fixed number of digits after the dot in your string :

var updatedTotal = (priceNumber * newKitAmount).toFixed(2);
