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

isExact

public boolean isExact()

Overrides:

isExact in class Complex

toExact

public Complex toExact()

Overrides:

toExact in class Complex

equals

public boolean equals(Object obj)

Overrides:

equals in class Complex

toString

public String toString()

Overrides:

toString in class Numeric

toString

public String toString(int radix)

Overrides:

toString in class Complex

neg

public final Numeric neg()

Overrides:

neg in class Complex

add

public Numeric add(Object y,
 int k)

Description copied from class: Numeric

Return this + k * obj.

Overrides:

add in class Complex

mul

 double y_re,
 double y_im)

log
