 # MN Twig Perversion plugin for Craft CMS
 
-Making twig do things it really shouldn't. Twig is not intended to be a general purpose programming language, and there are some things that really don't belong in the language. Tis plugin adds a few of those things anyway. Provides {% break %}, {% continue %}, and {% return %} tags for twig.

 A macro with a `{% return %}` tag will return whatever the return value is (which can be a complex expression). Any other output generated by the macro will be discarded.
 
+### Tests
+- **Numeric**
+  Test given value is numeric (behaviour like PHP 7 `is_numeric`).
+
+The test will return false for hexadecimal strings as this will be the default behaviour in PHP 7.
+(http://php.net/manual/en/function.is-numeric.php)
+
+#### Examples
+
+```Twig
+
+{{ 12 is numeric ? 'Yes' : 'No' }}
+{# Yes #}
+
+{{ '-1.3' is numeric ? 'Yes' : 'No' }}
+{# Yes #}
+
+{{ '0x539' is not numeric ? 'Hex. is not numeric' : 'N'}}
+{# Hex. is not numeric #}

+```
