  • Field Details

    • solutions

      public final double[] solutions
      Stores the roots of the equation. If the solutions are not complex, then the 2 solutions are real numbers stored in index 0 and index 1 of this array. If the solutions are complex(check field complex), then index 0 contains the real part of the first complex solution and index 1 contains the complex part of the first complex solution. Index 2 contains the real part of the second complex solution and index 3 contains the complex part of the second complex solution. If the content of the 4th index(solutions[4]) is 0, then the equation has real roots. If the content of the 4th index(solutions[4]) is 1,then it has complex roots.
