JSF Number Validation

Question

Is there any inbuilt number validator tag in JSF that checks whether an input entered in h:inputext field is a number?

The first question was answered. Edit

Answer 1

i8taken solution converts number into long without validation message (at least in my case: JSF2 / global messages per page). For proper validation message you can
1. check value in action method in bean;
or
2. use converter attribute for inputText:
