Class PiFraction

java.lang.Object
  PiFraction

 class PiFraction
extends Object

This class introduces fractions of π. The only actual difference between a Fraction and a PiFraction is their ouput formatting. Also, PiFraction is only used for outputting.

Constructor Detail

PiFraction

PiFraction(long nn)

Constructs a fraction from an integer.

Parameters:

nn - the integer (constructs fraction nn/1)

PiFraction

PiFraction(long nn,
           long dd)

Constructs a fraction from its numerator and denominator.

Parameters:

nn - nominator

dd - denominator

Throws:

IllegalArgumentException - Throws an exception if the denominator would be zero.

Method Detail

isEqual

boolean isEqual(PiFraction c)

Checks if this PiFraction is equal to another PiFraction.

Parameters:

c - comparand

Returns:

true if this PiFraction is equal to the comparand, false otherwise

toDegrees

long toDegrees()

Converts the angle from rads to degrees.

Returns:

magnitude in degrees of the angle given by this PiFraction

toTeX

String toTeX()

Prints this PiFraction formatted as TeX code.

Returns:

TeX code for this SRF; for example, -2π/3 yields -\frac{2\pi}{3}

toText

String toText()

Prints this PiFraction formatted as text.

Returns:

plain text description of this SRF; for example, -2π/3 yields -2*pi/3
