The Solaris version of Java uses the remainder() function to calculate
the floating point remainder operator. This function returns a value
that is within +/- half of the magnitude of the dividend.

On Windows, the fmod() function is used to calculate the result. This
function returns a number that has the same sign as the divisor and
magnitude less than the dividend.

It appears, based on recent mail from Richard Tuck, that Java defines the
behaviour of remainder() as the behaviour of the mod operator on floats.
Unfortunately, there is no remainder() function on Windows, so we will have
to code around this issue. The specification should be verified just in
case since the email I saw didn't quote actual text from the Java Language
