People have been having problems with functions to which tthey have passed
float types.  They solved this problem by uses doubles instead of floats.

Why does using doubles instead of floats work?  Because in ANSI C (which
MSC 5.1 is partly, somewhat, maybe, kinda, like ...) all float types are
promoted to doubles!!!  If you what to use floats and pass floats you must
use function prototypes.  Function prototypes stop the compiler from making
these type of automaic promotions.  

I found this out by reading the book:
	ANSI C: A Lexical Guide
	Published by Mark Williams Company
	Prentice Hall
	ISBN 0-13-037814-3

I just checked it out from the library today.  Learn something new everyday.
