Constructor Detail

DQuaternion

public DQuaternion()

DQuaternion

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

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

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.
