Hello,

the term "Gaussian function" usually indicates a certain kind of distribution
used frequently in statistics and physics. It can be implemented in its general
form by the following procedure definition:

	(define ((gauss a b c) x)
		(* a (exp (/ (sqr (/ (- x b) c)) -2))))

However, from your examples for function results I guess that you might
actually want a procedure rounding down to the next integer, which occasionally
goes by the name "Gaussian brackets", but is called "floor" in almost any
programming language, including Racket.

Ciao,
Thomas
