That's a nice explanation of what's going on, and I must admit i didn't think about co-processors etc. I don't necessarily agree with your conclusion, though. I do realise that with floating-points, you often get results that are not quite what you expected when you accumulate values or do limit checks using direct comparisons. (The "real code" I was working on doesn't do this quite as naively as you might think; what's attached is a much simplified example.) That's not the main problem here, though....

There is of course also a chance that the same issue will occur if using a "native" compiler under Windows. I'd appreciate if if someone would test this.
