a % b on floats is now the same as the IEEE remainder operation
(which is also the SVID remainder() ). It goes something like
this:
a) compute n = Math.rint( a/b ) that is, the nearest
whole number to a/b, with a tie going to an even number
b) then r = a - n*b is the remainder.
For example, this definition yields -2.5 for 12.5 % 7.5, because
12.5/7.5 gives 5/3, which rounds to 2, and 12.5 - 2*(7.5) is
-2.5
