| <tr><td><code>
| |
| <nowiki>{{Ifnumber|{{val|123|5}}|number|value "{{val|123|5}}" not numeric}}</nowiki> </code></td><td> {{Ifnumber|{{val|123|5}}|number|value "{{val|123|5}}" not numeric}}</td>
| |
| </tr>
| |
| </table>
| |
| | |
| ==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 <nowiki>{{formatnum:</nowiki> ''number'' <nowiki>|R}}</nowiki>.
