Re: YAJL and very precise number

:

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!

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).

Hi group,

I've been tasked with refactoring some API calls from our system to
various
websites and am implementing Scott Klement's excellent YAJLR4 service
program (thanks Scott!)

However, I'm a bit at a loss as to how I can extract coordinates from a
JSON file I receive.

More specifically, the latitude and longitude are represented as
follows:

"Location": {
"Lat_WGS84": 51.17456057389046,
"Lon_WGS84": 4.3991863572532086,
"X_Lambert72": 152128.06,
"Y_Lambert72": 207173.33
}

I can successfully find the Lat_WGS84 and Lon_WGS84 nodes, but I cannot
retrieve the full coordinates.

If I use yajl_get_string, it returns nothing (of course), but
yajl_get_number is truncated to 9 decimals whereas I need 14.

I could of course treat the JSON response as a string and simply scan
for
the first occurrence of "Location", but that would defeat the purpose of
having YAJL available.

Any suggestions?

Thanks in advance.

Peter
