I would rather choose for maintaining backward compatiblity, the *de facto behaviour* (return 0 on invalid values) as it is quite sensible for this kind of numbers.

It's quite strange though that Delphi compatibility is quite insistently adhered to (BTW a good decision IMO). The function has been in FPC stable (for presumably a while?) so I would really think hard before changing it. > And let's not beat about the bush: the main reason for the routine is to > show beginning programmers that their homework can be done using a fixed > function :-) Nice going to show beginning programmers how to break backward compatibility then ;) However, this is all just me 2c so it's up to the FPC devs to decide....
