I'm trying to fix the make-random-transaction so that it won't gen insane data. Harder done than said. > Could you please explain exactly what a division overflow means? if x=a/b and y =c/d then x/y = (a*d)/(b*c) If, after eliminating all common factors from the above, the if the numerator and/or denominator are *still* greater than 2^63 then its an overflow. > If this test-case really is going to over-flow on this operation then > we need to fix all the other tests to make "reasonable" random > gnc-numerics.
