How to validate bigint (10 digits or more like mobile no)?

Hi!

Greetings!

While  validating mobile number (for 10 digits) as integer, it  accepts only typical integer value (65535). 

Is bigint supported? other than through regex of course.

Was also looking for date, but couldnt find.

Thank you!
warm regards and gratitude for the nice framework that saves tons of work.
