Constructor Detail

SimpleFraction

public SimpleFraction(int numerator,
                      int denominator)

Create a fraction given a numerator and denominator.

Parameters:

numerator - the numerator

denominator - maxDenominator The maximum allowed value for denominator

Method Detail

buildFractionExactDenominator

public static SimpleFraction buildFractionExactDenominator(double val,
                                                           int exactDenom)

Create a fraction given a double value and a denominator.

Parameters:

val - double value of fraction

exactDenom - the exact denominator

Returns:

a SimpleFraction with the given values set.

buildFractionMaxDenominator

public static SimpleFraction buildFractionMaxDenominator(double value,
                                                         int maxDenominator)

Create a fraction given the double value and either the maximum error allowed or the maximum number of denominator digits.

Parameters:

value - the double value to convert to a fraction.

maxDenominator - maximum denominator value allowed.

Throws:

java.lang.RuntimeException - if the continued fraction failed to converge.

java.lang.IllegalArgumentException - if value > Integer.MAX_VALUE
