Constructor Summary public   NumberPrecisionReducer()      public   NumberPrecisionReducer(double scaleFactor)      A negative value for scaleFactor indicates that the precision reduction will eliminate significant digits to the left of the decimal point. (I.e. Method Summary public  double reducePrecision(double d)      public static  double scaleFactorForDecimalPlaces(int decimalPlaces)      Computes the scale factor for a given number of decimal places. A negative value for decimalPlaces indicates the scale factor should be divided rather than multiplied. public  void setScaleFactor(double scaleFactor)      Constructor Detail NumberPrecisionReducer public NumberPrecisionReducer()(Code) NumberPrecisionReducer public NumberPrecisionReducer(double scaleFactor)(Code) A negative value for scaleFactor indicates that the precision reduction will eliminate significant digits to the left of the decimal point. (I.e. the scale factor will be divided rather than multiplied). A zero value for scaleFactor will result in no precision reduction being performed. A scale factor is normally an integer value. Parameters:   scaleFactor - Method Detail reducePrecision public double reducePrecision(double d)(Code) scaleFactorForDecimalPlaces public static double scaleFactorForDecimalPlaces(int decimalPlaces)(Code) Computes the scale factor for a given number of decimal places. A negative value for decimalPlaces indicates the scale factor should be divided rather than multiplied. The negative sign is carried through to the computed scale factor. Parameters:   decimalPlaces - the scale factor setScaleFactor public void setScaleFactor(double scaleFactor)(Code) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
