[removed]How can I round up decimal values? [closed]

Answer 1

An easy way to do this is:

var num = 1724.1000000000001;
num = Math.ceil(num * 100) / 100;
alert(num); //  1724.11

How it works:

Ceil will round the value up. But you want to have 2 decimal numbers. The best way to do this is to:

1. Multiply the value with 100,
2. Round it up,
3. Divide it with 100.

Now you have an up rounded value with 2 decimals. This is what happens:

1724.1000000000001 * 100 = 172410.00000000001
round-up on 172410.00000000001 = 172411
172411 / 100 = 1724.11
