Methods Summary
public java.lang.Objectapply(java.lang.Object pLeft, java.lang.Object pRight, java.lang.Object pContext, Logger pLogger)
Applies the operator to the given value

    if (pLeft == null &&
	pRight == null) {
      if (pLogger.isLoggingWarning ()) {
	pLogger.logWarning
	  (Constants.ARITH_OP_NULL,
	   getOperatorSymbol ());
      }
      return PrimitiveObjects.getInteger (0);
    }

    double left =
      Coercions.coerceToPrimitiveNumber (pLeft, Double.class, pLogger).
      doubleValue ();
    double right =
      Coercions.coerceToPrimitiveNumber (pRight, Double.class, pLogger).
      doubleValue ();

    try {
      return PrimitiveObjects.getDouble (left / right);
    }
    catch (Exception exc) {
      if (pLogger.isLoggingError ()) {
	pLogger.logError
	  (Constants.ARITH_ERROR,
	   getOperatorSymbol (),
	   "" + left,
	   "" + right);
      }
      return PrimitiveObjects.getInteger (0);
    }
  
public java.lang.StringgetOperatorSymbol()
Returns the symbol representing the operator
