Is there a way to round a decimal place to the nearest whole in javascript?

Question

I have a number with decimal places and I am wondering if it's possible to round the decimal to the nearest whole using javascript?

My number is: 4.59

I need my number to round to: 4.60

Answer 1

Use Number.toFixed(number of decimal places):

var num = 4.59;
var rounded = num.toFixed(1);
