Not at the moment. There is currently no hardware or C support and adding
new types to numpy isn't trivial. You can get some limited Decimal
functionality by using python classes and object arrays, for instance the
Decimal class in the python decimal module, but the performance isn't great.

What is your particular interest in decimal support?
