To round down an integer, you should use Math.Floor().

Hi Alex,

You can use Math.round() method to round of the values, but sometimes didn't give the answer what you are expected. for eg Math.round(5/2) which gives answer 3 because if 5 is divided by 2 the quotient'll be 2.5 by using round() method if decimal value which is equal to .5 or more rounds the next highest value which here rounded as 3.

Instead of using Math.round you can use Math.floor() or Math.ceil() depending upon your requirement. If you need further details go through this link

Hope this helps.
