question: @ edu . umd . cs . findbugs . annotations . SuppressFBWarnings ( value = "FE_FLOATING_POINT_EQUALITY" , justification = "OK to compare floating point" ) protected void notifyTargetIntensityChange ( double intensity ) { double oldValue = mCurrentIntensity ; mCurrentIntensity = intensity ; if ( oldValue != intensity ) { firePropertyChange ( "TargetIntensity" , Double . valueOf ( oldValue ) , Double . valueOf ( intensity ) ) ; } }
target:  Change the stored target intensity value and do notification, but don't change anything in the hardware
