zend form float and integer validation

Question

I am using zend form. I want to validate a field and want to allow only flat and integer values in the field. It means user can either enter any floating value like 2.0 or 3.56, etc OR 4 or 7, etc. But I dont want to receive alpha numeric or alphabet input.

I have used digit validator but it only allows digits not floating number.

Can any body tell me how to put both validations together?

My code is as follows

$parent_affiliate_commission = new Zend_Form_Element_Text('parent_affiliate_commission');
$parent_affiliate_commission->setRequired(true)
            ->addFilter('StringTrim')
            ->addFilter('StripTags')
            ->addValidator('Digits')
            ->setAttrib('class', 'small')
            ->addValidator('StringLength', false, array(2, 100))
            ->setDecorators(array('ViewHelper', 'errors'))

It would be really easy to create and use a custom validator. You could validate simply by using PHP is_int and is_float functions and still do in the 'Zend way'.

By using the callback method I have validated the value in numeric.Because it will not allow the characters.

$inputFilter->add(
                $factory->createInput(
                        array(
                                'name' => 'proximity',
                                'required' => true,
                                'validators' => array(
                                        array(
                                                'name' => 'Callback',
                                                'options' => array(
                                                        'messages' => array(
                                                                \Zend\Validator\Callback::INVALID_VALUE => 'The proximity value should be numbers'
                                                        ),
                                                        'callback' => function  (
                                                                $value, 
                                                                $context = array())
                                                        {
                                                            $isValid = is_numeric(
                                                                    $value);
                                                            return $isValid;
                                                        }
                                                )
                                        )
                                )
                        )));
