public Complex()

Method Detail

jm

public final 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

km

public final 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
