FAQs

How can I tell someone to input only numbers?

You can instruct them to "please enter only digits", or use alternatives like "enter numerical characters only" or "numerical input only".

What is the difference between "digit" and "number"?

While often used interchangeably, "digit" refers to a single numerical symbol (0-9), whereas "number" can refer to a single digit or a combination of digits, like 25 or 100. Therefore, "please enter only digits" is more precise.

Is it better to say "enter digits only" or "only enter digits"?

Both are grammatically correct, but "please enter only digits" is clearer and more commonly used. It places the action (enter) first, followed by the restriction (only digits).
