Arguments are is, minimum and maximum.

For example, when the input must be 42:

{% validate id="number" type={numericality is=42} %}

And for a number within a certain range:

<input type="text" id="percent" name="percent" value="" />
{% validate id="percent" type={numericality minimum=0 maximum=100} %}
