What does Num command do?

The NUM() function is a versatile tool that enables the conversion of string inputs into their corresponding numeric values. This functionality is crucial in scenarios where data is initially presented in textual format but requires numerical manipulation for analysis or computation.

To utilize the NUM() function effectively, it's essential to ensure that the input string adheres to the strict rules governing numeric constants. These rules encompass the format and structure of numbers, ensuring that the conversion process yields accurate and reliable results.

For instance, the string "1234" would be readily converted to the numeric value 1234 by the NUM() function, as it conforms perfectly to the standards for numeric constants. However, strings containing alphabetic characters or special symbols, like "abc123" or "123$#", would not be valid inputs for this function.

The NUM() function's ability to handle various types of numeric formats, such as integers, decimals, and even scientific notations, underscores its versatility and usefulness in diverse data processing tasks.
