The modulus operator might be your friend here

ceil() is the function your looking for. Also it's opposite function is floor() is case you were wondering.

Edit: Also I think 2goto1 meant using Integer division. Added to the example.

Eg:

View.Set ("offscreenonly")
var t : int
var seconds : real
loop
    cls
    t := Time.ElapsedCPU
    seconds := t / 1000
    put "Miliseconds: ", t
    put "Seconds: ", seconds
    put "Ceil: ", ceil (seconds), " seconds"
    put "Floor: ", floor (seconds), " seconds"
    put skip
    put "Integer Division: ", t div (1000), " seconds"
    View.Update
end loop

Yes, you are looking for [tdoc]ceil[/tdoc] type rounding.

This is a common problem called the [url=http://en.wikipedia.org/wiki/Pigeonhole_principle]Pigeonhole Principle. It pops up all over the place, so learn it and remember it.

Pigeonhole Principle is a construct used in many proofs, not really "a problem". I don't follow how this is applicable to mod/ceil
