When a predicate takes an integer argument, it is not useful to check the range
of
the argument using min_integer and max_integer because the interpreter passes
the numbers to the predicate already wrapped. For example:
my_pred(222222222222). will be received as -1, which is within the range of
min_integer
and max_integer. (I tested this with Fedora Core 4 which has a max_integer of
about
256 million.)
Should the interpreter reject this input as a syntax error? Or convert it to a
float or something?
