Hi,

I am trying to find out how to get an absolute value for integer in ksh.

I tried using abs... but that doesn't work ! this is the workaround I did, but isn't there an inbuilt function to get absolute value for any variable !

Please help as i am new to unix

Thanks,

#!/usr/bin/ksh

ACTROWCNT=100
EXPROWCNT=100

if [ ${ACTROWCNT} -ge ${EXPROWCNT} ]; then
diff=`expr ${ACTROWCNT} - ${EXPROWCNT}`
else
diff=`expr ${EXPROWCNT} - ${ACTROWCNT}`
fi



if [ ${diff} -gt 100 ]; then
echo "should fail"
else
echo "Continue"
fi

exit 0
