Constructor Detail

Rational

public Rational(long numerator,
                long denominator)

The arguments to this constructor are long in order to represent all possible 32-bit unsigned integers. Parameters greater than 2 ^ 32 - 1 are not meaningful.

Parameters:

numerator - numerator of the Rational value

denominator - denominator of the Rational value

Rational

public Rational(int numerator,
                int denominator)

The arguments to the int constructor are treated as 32-bit unsigned integers.

Parameters:

numerator - numerator of the Rational value

denominator - denominator of the Rational value

Method Detail

getNumerator

public long getNumerator()

Returns the Numerator property.

getDenominator

public long getDenominator()

Returns the Denominator property.

toDouble

public double toDouble()

Converts to a floating-point value (numerator/denominator). May throw an ArithmeticException.

toLong

public long toLong()

Converts to a long value (numerator/denominator). May throw an ArithmeticException.

toString

public String toString()

Represents the Rational as a String in the form of "numerator/denominator".

Overrides:
