RealRootPower

 Method with 2 overloads

• RealRootPower​(System.​Double,​System.​Double,​System.​Boolean)

  Summary

  RealRootPower(System.Numerics.Complex,System.Numerics.Complex,System.Boolean) over Double.

• RealRootPower​(System.​Numerics.​Complex,​System.​Numerics.​Complex,​System.​Boolean)

  Summary

  A power to a rational exponent whose denominator is odd and below ten, as evaluation takes it:
  of a negative real, the real root to the numerator, (-8)^(1/3) = -2 and (-8)^(2/3) = 4,
  as Number.Pow's search for a good root finds it; of any other number, Power(System.Numerics.Complex,System.Numerics.Complex).
  The principal power gave 1 + 1.73i and -2 + 3.46i, and Math.Pow NaN over
  double, where evaluation has a real value. Whether the exponent is such a rational is only
  known where it is written, so the compilers choose this where they compile the power.
