Constructor Detail

SimpleFraction

public SimpleFraction(int numerator,
                      int denominator)

Create a fraction given a numerator and denominator.

Parameters:: 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

getDenominator
