Likewise FYI: XCSB decides on which division operator to use depending on 
where the result is to go. So:

	float	x
	int	y, z

	x = y / z

would use a floating point division because the expected result is a 
floating point. If you wanted to use integer division you would write:

	x = (int)(y / z)

This actually tells the compiler that you want to produce an integer as 
the result of the division.
