private boolean isGTEDelta(double value){
  return Math.abs(value) - Math.abs(mDelta) > -1.0e-5;
}

private boolean isGTEDelta ( double value ) { return Math . abs ( value ) - Math . abs ( mDelta ) > - 1.0e-5 ; }
indicates if the absolute value of the argument is greater than or equal to the delta value with accuracy to 14 digits of precision . this avoids rounding errors at 15 digits or precision or greater .
