qRound problem!

[SkripT]

Hi all, this time i have a little problem with qRound. Based on the tutorial:

int qRound ( double value )
Rounds value up to the nearest integer.

So, I think that the result of, for example, 256*2.22 (=568.32) should be 569 but the result that qRound gives me is 568. In my point of view this is not rounded up to the next integer. Anybody could explain me why? Thanks
