?!? – cubic functions are solved by calculators at least since the 67/97 era of the Seventies. Including real as well as complex solutions. There are several ways to solve such equations, the formulas are well know for centuries. Please take a look at Wikipedia on roots of cubic functions.

OK – solving quartic functions is a different story. ;-)

The calculator only provides numerical approximations and not exact answers. I would like a calculator to provide an exact solution. I can calculate it myself using the formulae.
