That's why I pointed out in my first reply that this thread had become
*about* integer division. It hasn't been clear what you're on about, and
I'm glad to see it clarified.

That's true of non-exceptional rationals but not of reals (by which I assume
you mean floating-point). With floats, it's possible (actually common,
alas) to have non-exceptional a, b and c such that a*b == c but neither c/a
== b nor c/b == a. Also possible to have a*b == c and c/a == b but not c/b
== a. Float arithmetic is also an information-losing process (see last
