Jonathan Coveney updated PIG-2764:
----------------------------------

    Attachment: PIG-2764-0.patch

So here is a first pass at this.[1] It works in the command line, but I'm not 
sure how to really test it. Would love to have eyes on it. I will upload to 
revieboard later.

There are a couple of choices that are suboptimal, but aren't really related to 
the core of the patch, so they can be fixed later (mainly just that I serialize 
it in a way that can be optimized...but given these aren't for performance but 
for accuracy, I'm not as worried).

[1] I needed a short respite from SchemaTuple work :) And I also wanted to see 
how difficult adding types is[2]

[2] difficult

> I think it would be useful for applications where precision is more important 
> than speed to have the option of using java's bigdecimal and biginteger types 
> natively.
