x

public Q x

y

public Q y

Constructor Detail

QI

public QI(Q real,
          Q imaginary)

This is the constructor. It initializes the x and y variables

QI

public QI(Q real)

This is the constructor. It initializes the x and y=0 variables

Method Detail

real

public Q real()

An accessor method. Returns the real part of the QI number. Note that there is no setReal() method to set the real part. This means that the QI class is "immutable".

imaginary

public Q imaginary()

An accessor method. Returns the imaginary part of the QI number

bet2

public static Q bet2(QI x)

Quadrat des Betrags

assign

public static QI assign(Q a)

Realteil besetzen, Imaginaeteil = 0

zero

public static boolean zero(QI x)

null ?

neg

public static QI neg(QI a)

negieren

add

public static QI add(QI a,
                     QI b)

This is a static class method. It takes two QI numbers, adds them, and returns the result as a third number. Because it is static, there is no "current instance" or "this" object. Use it like this: QI c = QI.add(a, b);

sub

public static QI sub(QI a,
                     QI b)

subtrahieren

conj

public static QI conj(QI a)

Konjugierte

mult

public static QI mult(QI a,
                      QI b)

multiplizieren

div

public static QI div(QI a,
                     QI b)

A static class method to divide QI numbers

read

public static QI read()

lesen

write

public static void write(QI z)

schreiben

copy

public static QI copy(QI z)

kopieren

power

public static QI power(QI z,
                       int n)

potenzieren

main

public static void main(java.lang.String[] a)
