doubleValue performance

[hrkalona]

I know that this is not related to the code on this repo, but I just wanted to ask if there is a way to implement a function that returns the double value approximation of a bigdecimal. The original implementation (at least for java 8 uses string operations in order to construct that representation which makes it incredibly slow).

If nothing can be done, then please go ahead and close this ticket.

Thank you very much
