Hi

Is there a way to control behavior of jsonencode. Example below, I want the run_id to be full integer. However jsone encode writes it in floating format.

apiData                   = struct;
apiData.run_id            = 1720787; 
apiData.run               = "BSCR_sbt rerun: PT Jan01_2023";
apiData.run_node_ids      = [20970];
apiData.scale_load_factor = 1000.1;
if length( apiData.run_node_ids)== 1    
    apiData.run_node_ids = { apiData.run_node_ids};    
end
jsonInp = string( jsonencode( apiData, 'PrettyPrint', true))

I got below, which the api doesn't accept float for run_id

jsonInp =

"{

"run_id": 1.720787E+6,

"run": "BSCR_sbt rerun: PT Jan01_2023",

"run_node_ids": [

20970

],

"scale_load_factor": 1000.001

}"

Is it possible for you to store that number as an integer instead, for example

apiData.run_id = int64(1720787);

?

Because then

apiData                   = struct;
apiData.run_id            = int64(1720787); 
apiData.run               = "BSCR_sbt rerun: PT Jan01_2023";
apiData.run_node_ids      = [20970];
apiData.scale_load_factor = 1000.1;
if length( apiData.run_node_ids)== 1    
    apiData.run_node_ids = { apiData.run_node_ids};    
end
jsonInp = string( jsonencode( apiData, 'PrettyPrint', true))
jsonInp = 
    "{
       "run_id": 1720787,
       "run": "BSCR_sbt rerun: PT Jan01_2023",
       "run_node_ids": [
         20970
       ],
       "scale_load_factor": 1000.1
     }"
