I need a pointer to an algorithm for finding the REAL roots of a polynomial of degree 4 or less. Working code would be wonderful, pointers would be helpful. We already have a routine to find all the COMPLEX roots of an arbitrary polynomial, but this is a lot more general (read: slower) than I would prefer, and has a tendency to make floating point exceptions. Thanks, -Mike
