Sturm's theorem (up to cubic equations)

Calculate the number of real solutions to a cubic equation using Sturm's theorem.


(1) Choose either quadratic or cubic equation.
(2) Input each coefficient and constant term.
(3) Enter the two numbers that specify the open interval, separated by ",".
(4) Display the real number solution for the specified equation and open interval.

In rare cases, conditions that require extreme precision may return the wrong number of items. (A problem with the precision of the "formula" action?)
