I think this is the same result you get with a plain (64-bit) long. The / and % operators in C++ produce a quotient rounded towards 0, so (f(1) - b) / DECKSIZE == 0, and the corresponding remainder is negative.
I'm not that familiar with perl, but I guess it uses the mathematically more sane definition of always rounding the quotient towards -infinity,
Every language has its own definition :-) https://en.wikipedia.org/wiki/Modulo_operation#In_programming_languages Ĝis, m _______________________________________________ gmp-bugs mailing list gmp-bugs@gmplib.org https://gmplib.org/mailman/listinfo/gmp-bugs
