The function commonly used to convert a string representation of a number to a numeric data type in LabVIEW is indeed the String To Number function. This function takes input in the form of a string and interprets it, allowing for conversion to various numeric data types such as integer or floating-point numbers.

Using this function is important when working with data from external sources that may be represented as text but need to be processed as numbers for calculations or analysis within LabVIEW. It is particularly useful in applications where numerical data is input through user interfaces or read from text files.

The other options do not serve this specific purpose. The Number To String function, for example, is utilized for converting numeric data types back into string representations, making it the opposite of what is needed in this context. The terms Convert String and String Conversion are not designated functions within LabVIEW, which means they do not perform any conversion operations related to numeric data types.
