[%] and [mod] treat the sign differently. [mod] is monotonic but [%] is symmetrical about zero.

Hello,
If you want to calculate the modulo of a negative number, you get a different result if you use the 'mod' object or 'expr' with %.
-1 4 | | mod | 3
-1 4 | | expr $f1 % $f2 | -1
I guess this is a bug in expr ?

thank you andy.
i guess it is a bug anyway, not in the objects, but in the
documentation. both open the same helppatch with no mention about the
difference.
