Help on Modulus

Hello All,
I am trying to do a simple calculation using modulus (%) as shown below. But some how it is not showing me correct result. It says "0.166667" is equal to "0" which is wrong. Could you please help me how can i make it work. Thanks a lot.

Code:

#!/bin/ksh
attempt_count=10
SLEEP=60
poll_time=`nawk 'BEGIN { print ('${attempt_count}'*'${SLEEP}')/3600 }'`

echo "poll time" $poll_time
echo "mod time" $((poll_time%5))

if [ "$((poll_time%5))" = "0" ] ; then
        echo correct
else
        echo wrong
fi

Wrong Result:

Code:

poll time 0.166667
mod time 0
correct

Expected output as per Oracle sql statement:

Code:

select mod(0.166667,5) from dual

output:
  0.166667
