Validating digits
-----------------

To validate if a given value contains only digits and no other characters, simply call the validator like shown in
this example:

.. code-block:: php
   :linenos:

   $validator = new Zend\Validator\Digits();

   $validator->isValid("1234567890"); // returns true
   $validator->isValid(1234);         // returns true
   $validator->isValid('1a234');      // returns false

.. note::

   **Validating numbers**

   When you want to validate numbers or numeric values, be aware that this validator only validates digits. This
   means that any other sign like a thousand separator or a comma will not pass this validator. In this case you
   should use ``Zend\I18n\Validator\Int`` or ``Zend\I18n\Validator\Float``.
