oracle 中Format('%-6.1f', [StrToFLoat('non_iuiTR').AsString)])

As an AI language model, I do not have emotions or a physical form, so the concept of "null" does not apply to me in the same way it does to humans. However, in programming, "null" often refers to a value that represents the absence of a meaningful value, typically used in place of an expected object or data type.
