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
