There is no function to do it.  The compiler just knows how to do it.

	int i;
	float f;

	i = f;		/* truncates */
	i = f + 0.5;	/* rounds, for positive numbers */

You may want to look up the floor() and ceil() functions for doing
various rounding operations on doubles before letting the compiler
convert it to an int.
