Update of bug #43041 (project octave):
Status: Fixed => Confirmed
Summary: isprime(7i) returns true => isprime(5i) returns true
_______________________________________________________
Follow-up Comment #2:
The bug is not that isprime(7i) is true, because it is, but that isprime(5i)
is true (which it's not, since 5i = (2 + i)(1+2i).
I'll patch this. There's no reason why this function should be restricted to
positive integers.
