You could install bc (`apt-get install bc` or from source if you are using the original firmware)

Better version:
echo “`df /data | grep -vE “^Filesystem” | awk ‘{ print (81/$2)*$3+16 }’`/1″ | bc > /sys/devices/platform/wdc-leds/leds:wdc-leds:fuel-gauge/brightness

Simple disk space indicator:
(add to crontab)
*/10 * * * * root echo “0.0000002035*`df /data | grep -vE ‘^Filesystem|tmpfs|cdrom’ | awk ‘{ print $3 }’`/1″ | bc > /sys/devices/platform/wdc-leds/leds:wdc-leds:fuel-gauge/brightness
