if you want to turn it into a function:
var number = 27/7; // Three decimal places console.log(round(number, 3)); function round(number, decimal_places) { return Math.round(number * Math.pow(10, decimal_places)) / Math.pow(10, decimal_places); }
Output:
3.857

Hey I think it’s Math.round(number);
and put the number where it says “number”
But here is the link I found it from: https://www.w3schools.com/jsref/jsref_round.asp
Hope this helps!
Rounding to 3 decimal places looks something like this:
Math.round(x*1000)/1000
