# Solver

## Object Hierarchy:

## Description:

public class Solver : Object

Math expression solver.

Add any required equations to equation_manager or use add_expression, then solve will add a new equation and returns the resulting MathResult.

     var s = new Solver ();
     s.add ("x=3*5");
     var res = s.solve ("2*x+7*x^2");
     var c = (MathConstant) res;
     // Result will be 1605
     stdout.printf ("%g", c.real ());
