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:
