Rounding up figure

Hi there,

I would like to get help on how to round up the total.

For examples..

fieldname1 = 3.2
fieldname2 = 1.8
the total will be 5.76..

How can i implement the code to display the round up figure of 6?
I want to implement it to all, for example, if the total is 5.02, i want it to display as 6 as well.

Thank you
