Which of the following is NOT a delimiter value mentioned for numbering?

In the context of numbering, delimiters are characters used to separate or organize different segments of value, typically to enhance readability or structure the data.

A hyphen, underscore, and period are all characters that can effectively serve as delimiters in various scenarios. For instance, a hyphen is commonly used in phone numbers and in some numeric sequences, while a period can be found in decimal numbers or separating parts of a version number. The underscore is often used in computer programming and data handling to create clear delimiters in names or identifiers where spaces cannot be used.

However, the comma is typically used as a separator in lists or to denote thousands in large numbers. In this context, it's important to note that while commas serve a different purpose in numeric formats, they are less common as delimiters for numbering compared to other characters mentioned.

Therefore, the correct answer is that the comma is less recognized as a delimiter value specifically for numbering compared to a hyphen, underscore, and period.
