Right. It's clearly too early in the morning to think about such 
implications :P
In that case: Thorsten, do you have tests that could go with the new 
Frac() implementation? Something simply that checks the results and does 
a Halt() if something is wrong would be sufficent. This way I can be 
sure that my conversion to FPC's syntax will be correct.

Oh, and before I forget it: would you *please* stop top posting? (Except 
you have a valid reason for it like being blind and using a screen reader)
