Re: YAJL and very precise number

10x faster if you include the float transform?

Not that it matters that much since your code is not available to the rest of us I guess.

The performance turned out to be something like 10 times faster than YAJL.
After calling the parse() procedure you might code something like:

latitude = %float(jsnGetVal('/Lat_WGS84'));

Peter,

Looks like Scott provided a solution. With the JSON parser I wrote, I felt
that the API would be much simpler if I had only 1 procedure return node
values as VARCHAR type, and let the RPG programmer use %float(), %dec(),
%int(), etc. to transform it to the appropriate data type. As a bonus, it
turned out that it performed something like 1

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
