Behavior of numeric::to_int() and numeric::to_long()
by Roberto Bagnara 01 Oct '02

01 Oct '02

These methods, and the corresponding functions taking the argument as a const numeric& parameter, when something goes wrong print a line of the form Not a 32-bit integer: -9223372028264841216 on cerr and exit the program. Wouldn't throwing a suitable standard exception (like std::domain_error) be a better option?

Last in this series: behavior of irem()
by Roberto Bagnara 01 Oct '02

01 Oct '02

The function numeric irem(const numeric &a, const numeric &b) prints "Division by zero." and exits when b is zero. As in all the other cases reported, this makes it more difficult to write robust software. Of course, we can check b before calling irem() (and we are doing it) but this impedes performance for no reason, since the test on b must be re-done anyway in order to decide whether to print the error message and exit.

Behavior of numeric::is_prime()
by Roberto Bagnara 01 Oct '02

01 Oct '02

In an attempt to invent documentation for the GiNaC facilities we use, we came across the following inconsistency in the behavior of the method bool numeric::is_prime(void) const and the function bool is_prime(const numeric &x), whereby exit(1) is called (via cl_abort()) if the number to be tested is a non-positive integer. I believe is_prime() should return false in this case, as it does for, e.g., -2/7, 2/7, 3*I, and 2.8943657489. All the best Roberto P.S. I am not including a patch since this issues may be dealt with either in CLN (which I believe is the better option) or in GiNaC. -- Prof. Roberto Bagnara Computer Science Group Department of Mathematics, University of Parma, Italy http://www.cs.unipr.it/~bagnara/ mailto:bagnara@cs.unipr.it
