Fwd: Re: min and max in arithmetic ?

[Jasper Taylor]

OK I have managed to do this now! So far the result is always a float but I 
could see how to make integers too.

How do I submit a patch?

I guess so, but I want it in the arithmetic evaluator so I can go, eg.,

        RealSize is min( max( LIC, Size ), 10 ).

to get the equivalent of

max(Size, LIC, Size1),
min(Size1, 10, RealSize).

Ie. implement min and max in the same way that, eg., trig functions are
implemented (as in Sicstus) -- this is what I tried (and failed) to do

...please?
