Hi all,
Here's a patch that adds some tests for odd?, even?, lcm, gcd, quotient,
modulo, remainder and arithmetic-shift.
According to R5RS and R7RS odd?, even?, lcm, gcd, quotient, modulo and
remainder accept only integer values (which may be inexact).
Also, these procedures shouldn't accept +inf.0 or +nan.0 and, in case of
arithmetic-shift, odd? and even?, convert them to some unknown value
(looks like it's 0, but that's probably a C compiler/hardware detail).
Cheers,
Peter
