• Method Detail

  • 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

  • isExact

    public boolean isExact()

    Overrides:
