| Part | Description |
| Result | Required; any numeric variable. |

| Both expressions are numeric | Add. |
| Both expressions are String | Concatenate. |
| One expression is a numeric data type and the other is any data type except Null | Add. |
| One expression is a String and the other is any data type except Null | Concatenate. |
| One expression is an Empty data type | Return the remaining expression unchanged as result. |
| One expression is a numeric data type and the other is a String | A Type mismatch error occurs. |
| Either expression is Null | The result is Null. |
Example
