How do I detect if a string has only numbers, and no letters or words at all? From what I know, it’s possible.
Thanks.
You can do this
if tonumber(string) then
-- string only has numbers
end
Can the string include plus or minus sign, the decimal marker (.), hexadecimal using 0x prefix, "inf", "infinity", "nan", or "nan(id)"?
If so then the above reply would work.
If not and you’re actually looking for to check if the string has only numerical digits (0-9) and nothing else then you could try pattern matching (using string.match) and then use the pattern ^%d+$ if empty strings are not accepted or ^%d*$ if so.
Yeah, that works very well, thanks
Yes, that can also be done, I am just new to LuaU, and I am still unsure on how to use the string library.
