Is HOUR_SELECTED a floating-point number (e.g. 11.99999999999)? If so, you need to account for that in your comparison.

Hi,

 

I have some dialplan code that is trying to convert 12 hour time with AM/PM to 24 hour format. The code has something like this:
Exten => 2,1,ExecIf(${MATH(${HOUR_SELECTED}<12)}?Set(HOUR_SELECTED=${MATH(${HOUR_SELECTED}+12,int)}))

 

Earlier on in the dialplan HOUR_SELECTED is set to 12. When they press option 2 they are selecting PM. If the time is from 1PM to 11PM then I want to add 12 to the number (so if it's 1 make it 13 etc.). When I run the above the logs show the result as false yet if the user sets HOUR_SELECTED to 12 then after this line of dialplan code it gets switched to 24. What am I doing wrong here?

 

The exact DP code is:

Exten => 2,     1, Noop(BEFORE CHECK HOUR_SELECTED is ${HOUR_SELECTED})
 same =>        n, ExecIf(${MATH(${HOUR_SELECTED}<12)}?Set(HOUR_SELECTED=${MATH(${HOUR_SELECTED}+12,int)}))
 same =>        n, Noop(AFTER CHECK HOUR_SELECTED IS ${HOUR_SELECTED})

 

And the output of the logs is:

[Feb 13 10:46:18] VERBOSE[1580][C-00007bc6] pbx.c: Executing [2 at am_pm_select:1] NoOp("SIP/204.145.219.31-000081c6", "BEFORE CHECK HOUR_SELECTED is 12") in new stack

TIA.
