Interesting.
I don't know what the ISO standard say, but mathematically a a % b will
always return you an integer 0 <= a%b < b (since there are no negative
numbers in canonical representation of Z/bZ). I guess perl/python/tcl
ddecided to adhere to the mathematical definition.
ISO C truncates towards zero. It specifically says in 6.5.5 Multiplicative Operators:
If the quotient a/b is representable, the expression (a/b)*b + a%b shall equal a.
So -27 % 7 yields -6.
Yeah, I read that in the bug report and confirmed that as the intended behavior in C. What I meant was 'regardless of what the ISO standard says, thats not a standard mathematical definition.'
