Close, but that's technically not true in the case where abs(a/b) > long.max. (The integer doesn't have to fit into a 'long').
But if real is 79-bit long (as on Intel), the largest integer that could fit without loss in 1 << 63, and that would fit in a long. Are you saying r could spill into large integers that cannot be represented without loss?
In IEEE754, r= a % b is defined by the mathematical relation r = a – b * n , where n is the integer nearest the exact number a/b ; whenever abs( n – a/b) = 0.5 , then n is even. If r == 0 , its sign is the same as a.
I take it D does not define a % b the IEEE 754 way (that's why I eliminated that mention). Is that correct?
