The differentiability class is a measure of the highest order of derivative that exists continuously for a function.

Formally: ( function with a domain as an open set on and ) The function is said to be of (differentiability) class if the derivatives , , , exist and are continuous. The function is said to be infinitely differentiable, smooth; or of class , if it has derivatives of all orders.
