This old chestnut! It's a common problem in practice. As I recall, the behaviour of C's % operator allows implementations to yield either behaviour. I just checked ISO 9899:1999 which defines fmod. It specifies that the result of fmod(x,y) should have the same sign as x. Interesting.
Interesting, perhaps. Surprising, no. fmod() is basically there for the sake of sin(), cos(), and tan() (or any other periodic and either symmetric or antisymmetric function). _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
