Re: YAJL and very precise number

[Scott Klement <rpg400-l@xxxxxxxxxxxxxxxx>]

Hi Peter,

Currently yajl_get_number() converts numbers to packed(30: 9) fields.  
At the time I first ported YAJL to the system (more than 10 years ago 
now) I still had to support V5R3, which could only support 30 digit 
numbers, so this seemed like a good compromise.

Perhaps I could add a new subprocedure that does the same thing but 
returns a larger size such as packed(63: 15).
