Depending on what you want to do one of
	(int) realnumber
	(int) (realnumber + 0.5)
might be suitable. Of course, you might want to consider whether or not
realnumber is positive or negative as well. And if you wanted to stay
in floating point, floor() and ceil() in the standard C library are
probably useful.

Anyway, ask this sort of question in a C programming newsgroup next time.
This is rather off topic in these parts.

Also you might want to consider getting a basic C book. Unless one is
learning C by trial and error there is no realistic alternative ;)
