Solving algebraic equations

The equation solver can solve algebraic equations  an*xn + an-1*xn-1 + ... + a1*x + a0 = 0  with high precision. The coefficients are defined in a data grid.

Features:

1. Calculation of solutions of equations from 1^st to 10^th degree.
2. The precision which is used for calculating the solutions of an equation is adjustable. For example up to 2000 decimal digits are possible for equations up to 4^th degree.
3. For quadratic equations exact solutions can be displayed as a mathematical formula.
4. For cubic equations and equations of higher degree exact solutions are possible if rational solutions exist.
5. Complex coefficients and complex solutions are possible.
