SET /A command and rounding

[marcorocchini]

Hi, please help the cat thanks

        for /f "tokens=1,2 delims=^=" %%g in ('ffprobe64bit333.exe -hide_banner -loglevel fatal -pretty -select_streams v:0 -show_streams     "%cd%\avsInput.avs"') DO (
	if "%%~g"=="duration_ts" set "NumberOfFrame=%%~h")
        
       set /a "NumerOfTotalFrames=%NumberOfFrame%/2"

the output of my NumberOfFrame is 3531, but 3531 / 2 = 1765,5 that set /a round to 1765

I wonder: is there a way to tell to the set /a that have to be round "over" so that the final result is 1766 [and not 1765, I need 1766] ? tHANKS

Add 1 before dividing by 2.
