Psstt... Dividing is not associative for the reals.
- kaslai 4y agoI think the original intent was referring to the fact that given the same operand, the order of multiplication and division shouldn't matter, e.g. A * X / X should give the same result as A / X * X, but in reality they can give different results when done by a computer due to precision limits, overflow, etc.
- BeetleB 4y agoAh that makes sense.
