In every compiler, interpreter, and CPU that I've ever used, the remainder has

compilers could do different things?


In C89 the result of integer division and modulo with negative operands were
implementation-defined -- the result of division could be either floored or
truncated, and the modulo result also varied to match.

This was fixed in C99, with division results always being truncated (whereas
Python uses the floor).
