## com.bbn.openmap.geo
Class Quadratic

    java.lang.Object
      com.bbn.openmap.geo.Quadratic

public class Quadratic
extends java.lang.Object

Computes 0 to 2 real roots of the quadratic:

       a*x^2 + b*x + c = 0

See http://web.cs.mun.ca/courses/cs2710-w02/lab5/assignment/assign5.html. http://www.1728.com/quadratc.htm

Access the roots as a double iterator with methods hasNext() and next().

Constructor Summary
`Quadratic(double a, double b, double c)`

Method Summary
`double` | `eval(double x)` Evaluate the Quadratic at x.
`boolean` | `hasNext()`
`static double` | `linear(double a, double b)` Returns the solution, x, to the equation a*x+b = 0
`static void` | `main(java.lang.String[] args)`
`double` | `next()`
