In traditional C, the result of applying / or % to negative integers is
implementation dependent and hence undefined at the language level. Likely
it will be remainder type semantics rather than modulus type semantics
because most machines do things that way by default, but on the ICL1900
series C gave modular semantics, since that's the way the machine was.
I think this is unchanged in the ANSI C standard, can someone confirm this?
