      public DQuaternion(double real, double imag, double jmag, double kmag)

  • Method Details

    • re

      public RealNum re()
      Description copied from class: Quantity
      The value of the real component, as a RealNum. The unit() is not factored in, so you actually need to multiply by unit() to get the true real component.
      Overrides:
      re in class Quantity

    • doubleValue

      public double doubleValue()
      Description copied from class: Quantity
      The value of the real component, as a double. This is relative to the unit().dims - i.e. unit()/doubleValue() is factored in.
      Overrides:
      doubleValue in class Quaternion

    • im

      public RealNum im()
      Description copied from class: Quantity
      The value of the imaginary component, as a RealNum. The unit() is not factored in, so you actually need to multiply by unit() to get the true imaginary component.
      Overrides:
      im in class Quantity

    • doubleImagValue

      public double doubleImagValue()
      Description copied from class: Quantity
      The value of the imaginary component, as a double. This is relative to the unit().dims - i.e. unit()/doubleValue() is factored in.
      Overrides:
      doubleImagValue in class Quaternion

    • jm

      public RealNum jm()
      Description copied from class: Quantity
      The value of the "j" component, as a RealNum. The unit() is not factored in, so you actually need to multiply by unit() to get the true "j" component.
      Overrides:
      jm in class Quantity

    • doubleJmagValue

      public double doubleJmagValue()
      Description copied from class: Quantity
      The value of the "j" component, as a double. This is relative to the unit().dims - i.e. unit()/doubleValue() is factored in.
      Overrides:
      doubleJmagValue in class Quaternion

    • km

      public RealNum km()
      Description copied from class: Quantity
      The value of the "k" component, as a RealNum. The unit() is not factored in, so you actually need to multiply by unit() to get the true "k" component.
      Overrides:
      km in class Quantity

    • doubleKmagValue

      public double doubleKmagValue()
      Description copied from class: Quantity
      The value of the "k" component, as a double. This is relative to the unit().dims - i.e. unit()/doubleValue() is factored in.
      Overrides:
      doubleKmagValue in class Quaternion
