Interpreter accepts integers exceeding max_integer

When a predicate takes an integer argument, it is not useful to check the range 
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 
and max_integer. (I tested this with Fedora Core 4 which has a max_integer of 
256 million.)

Should the interpreter reject this input as a syntax error?  Or convert it to a 
float or something?
