Float values to REST API from Hp Nonstop

sailokesh — Tue, 18 Feb 2025 10:07:55 GMT

Issue: Not able to send float values in restapi payload from Tandem to External world.

CSL-Studio: Data type in CSL studio is float

Generated Stub file:

TEMPERATURE NATIVE-4

On Tandem we have data type PIC 9(4)V9(3).

When we try to move these values to the TEMPERATURE NATIVE-4 We are getting only the first value before point

MOVE 1.4 TO TEMPERATURE

Then I am getting only 1 in TEMPERATURE

VHS Error:
Invalid input values

When we change the stub file:
TEMPERATURE PIC 9(1)V9(3)

Values looks good on Tandem side,

MOVE 1.4 TO TEMPERATURE

Here 1.4 in TEMPERATURE

But the value is not passing to Server, It is coming as Zero.
"temperature": 0.000000

Any help is appriciated and Thanks in advance.

@sailokesh

The issue is likely due to a data type mismatch between the Tandem system (PIC 9(4)V9(3)) and the external API. The key problems are:

Firstly that might be NATIVE-4 truncates the decimal part, keeping only the integer value.

Secondly, PIC 9(1)V9(3) correctly retains the decimal on Tandem but sends 0.000000 in the API.

Possible solutions are:

Try using NATIVE-8 instead of NATIVE-4.>> Explicitly convert the value using FUNCTION NUMVAL(TEMPERATURE).>> Ensure the API expects float values correctly formatted (e.g., as a string).>> Ensure the API expects float values correctly formatted (e.g., as a string).>> The bebug the outgoing JSON payload to confirm the value before transmission.

I hope it helps. Let me know..

Hi @Mr_Techie

Thank you for your reply. It's not working.

When I put native-8, I am getting length invalid.

My server is expecting float values.
