that's interesting. elk-scheme says about this:
Actually, R5RS says:
An operation may, however, return an exact result if it can prove
that the value of the result is unaffected by the inexactness of its
arguments. For example, multiplication of any number by an exact
zero may produce an exact zero result, even if the other argument is
inexact.
In some environments this sort of thing can be a fast path. This
actually is exactly what some people really do not like about R5RS.
Personally, the fact that both Stalin and mzscheme actually exist
suggests a curious sort of happiness...

This reminds me of pop music, "I'm no fucking Buddhist, but this is
enlightenment"... :?
(exact? (* 0 440.0))
#f
guess something to be fixed, if #t is the R5RS answer...
