Hm. This seems like a bug:
% integer rnd
% print -- $(( rnd = ((29.1 % 13.0 * 10) + 0.5) ))
31.500000000000014
Shouldn't the result of the $(( ... )) be an integer because rnd has been
declared as an integer?
I had to do this instead:
diff --git a/Test/C01arith.ztst b/Test/C01arith.ztst
index 59d182a..8da17f7 100644
