Math functions for dccQuantities classes

I'm currently working on supporting dccQuantities together with SymPy in dcclib.
Normal calculations with the magic functions provided by your classes are already working.

Now I need to support more complex math functions like math.sqrt and math.Pow.

Could you provide implementations of the common math functions found in Metas Unclib for your classes and have them in your library?

With these functions I would be able to create a mapping for the internal SymPy math functions and allow for more complex formulae with uncertainty propagation like this:
