WebJul 15, 2011 · By sorting the numbers, you group values of similar magnitude together, and by adding them in ascending order you give the small values a "chance" of cumulatively reaching the magnitude of the bigger numbers. Still, if negative numbers are involved it's easy to "outwit" this approach. Consider three values to sum, {1, -1, 1 billionth}. WebNov 7, 2013 · Sum of real numbers is associative and commutative. Floating-points aren't real numbers. In fact you just proved that their operations are not commutative. It's pretty easy to show that they aren't associative too (e.g. (2.0^53 + 1) - 1 == 2.0^53 - 1 != 2^53 == 2^53 + (1 - 1)). Hence, yes: be wary when choosing the order of sums and other ...
