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.
I could not find any trace of it on the embarcadero web site. Wouldn't
we be taking into account a compatibility with something which does
not exist, by any chance?
When there is no Delphi-compatibility needed there is still backwards
compatibility to code developed in FPC.

Sven
