This particular problem could obviously be resolved by adding a
currency-specific version of abs()

Can i ask to add overload function for ABS(Currency) be a feature
request
in FPC?

Yes, please add an entry in the bugtracker.

Note that this requires compiler patching, because abs() is internal
(it can be used in constant expressions). I would personally argue to
do away entirely with the "treat currency as a floating point type on
i386 so it can use the 80x87", and instead map it implementation-wise
to int64 like on all other platforms. You may lose a bit of
performance, but you'll gain consistency. And you won't need hacks
like this (which, as mentioned before, only solves one particular
use-case, and so I'm not very much in favour of doing this).

As far as I know, Currency is always a scaled int64, and didn't
interpret the
request as a request to change that. I missed probably part of the
argumentation but on the face of it, having a ABS(Currency) seems like a
reasonable request.

No, Currency is based on Extended on i386 and x86_64 (except win64!).

Sven
