Postman script - Calculate sum and return the value to 2 decimal places

Question

In a Postman test script, I am trying to get a specific value using a simple calculation and return that value, in order to use it in a subsequent parts of the request.

let expectedDpay = temp.payPlanPremiumAmount;
let expectedDpay = (expectedDpay*12.5)/100;

The expected value I get is, for example 136.125 but I would like it to return to 2 decimal places, 136.13.

How can this be achieved?

`expectedDpay = Math.round((expectedDpay*12.5)/100).toFixed(2)` ? — Danny Dainton, Oct 20 '22 at 21:05
@DannyDainton, close :) - that will round to an integer *first*, then apply the two decimal places (eg. resulting in `136.00`). OP wants it "colloquially rounded" to 2 decimal places. — Frank Alvaro, Oct 20 '22 at 21:17
That was a guess, I didn't actually try it - That's why I left it as a comment — Danny Dainton, Oct 20 '22 at 21:32

Try num.toFixed(2) to round to 2 decimal places.

expectedDPay = ((expectedDPay * 12.5)/100).toFixed(2);
