protected org.apache.poi.hssf.record.formula.eval.ValueEvalToNumericXlatorgetXlator()
this is the default impl for the factory method getXlator of the super class NumericFunction. Subclasses can override this method if they desire to return a different ValueEvalToNumericXlator instance than the default.
