Template:Isnumber
This template tests whether a value is a number.
Usage
Use {{Isnumber|123}}, which will return the input value "123" if it is a number, and blank otherwise.
To do something if the input is indeed a number, encapsulate this template within an "if" ParserFunction, for example:
{{#if:{{isnumber|123}}|is a number|not a number}}-> is a number
Examples

Notes
This template will not recognize formatted numbers, which is by design since formatted numbers will break expression parsers. To remove the formatting from a number, you can wrap the number first in:
{{formatnum:number|R}}.
| Code | Result |
|---|---|
{{isnumber|1,000.50}} |
|
{{isnumber|{{formatnum:1,000.50|R}}}} |
1000.50 |
