In short, yes.

Ruby's behavior for quotient, modulo and remainder was mixture of C,
Python, Scheme, etc.  And was pretty inconsistent.  After days of
pondering, I finally decided the behavior of fmod(3m) to be followed.

       The fmod() function computes the remainder of dividing x by
       y.  The return value is x - n * y, where n is the quotient of
       x / y, rounded towards zero to an integer.

So I hacked Numeric classes, and made them consistent.  I still have
to update the test suite.  `make test' fails now.

We lost old % (modulo) behavior, but who on earth use modulo for
nagative operands. ;-)
