Re: YAJL and very precise number

[Scott Klement <rpg400-l@xxxxxxxxxxxxxxxx>]

Hello Peter,

I've updated my website here:  https://www.scottklement.com/yajl/

If you download the latest version of YAJL for IBM i 7.1+, it now has a 
subprocedure called yajl_get_bignumber() that will return a 
packed(63:20) -- so more than the 15 decimal places you asked for.  
Simply change your code to call yajl_get_bignumber() in place of 
yajl_get_number() and you'll have the full precision.

Good luck!
