Method Details

getCurrentFactor

protected BigRational getCurrentFactor()

Description copied from class: SeriesCalculator

Returns the factor of the highest term already calculated.

When called for the first time will return the factor of the first term (index 0).

After this call the method SeriesCalculator.calculateNextFactor() will be called to prepare for the next term.

Specified by:

getCurrentFactor in class SeriesCalculator

Returns:

the factor of the highest term

calculateNextFactor

protected void calculateNextFactor()

Description copied from class: SeriesCalculator

Calculates the factor of the next term.

Specified by:

calculateNextFactor in class SeriesCalculator

createPowerIterator

 MathContext mathContext)

Description copied from class: SeriesCalculator

Creates the PowerIterator used for this series.

Specified by:

createPowerIterator in class SeriesCalculator

Parameters:

x - the value x

mathContext - the MathContext

Returns:

the PowerIterator
