Yes, I share the judgment of Kohei and Markus that the rounding errors problem can't be solved for all computations without losing performance. Infinite precision is too expensive. Current behavior is not problematic if we keep rounding errors small. It is not always the case and we should try to avoid the cases where rounding errors gives final errors that are not small. That is the challenge of Numerical Analysis, finding correct results with false computations. ;-) In comment #2 of https://bugs.freedesktop.org/show_bug.cgi?id=80732 I showed that it is possible to make better computations of MOD() and QUOTIENT() functions. At least in the cases reported here. Best regards.
