Sh Script Help - Grading Papers
How do I make the average grade show a decimal point?
Instead of showing Average Grade = 33%. I want it to show Average Grade = 33.3333%
This is my code so far:
#!/bin/bash
read -p "Number of Papers To Grade: " numpap
av=$numpap
while [ $av -gt 0 ];
do
av=$(($av - 1))
echo "Enter a Number (1-100): "
read num
if [[ $num -ge 1 && $num -le 100 ]] ; then
echo ""
else
print "NOT in 1-100 range"
av=$(($av + 1))
total=$(($total - num))
fi
total=$(($total + num))
done
averag=$(($total/$numpap))
echo "Average Grade = $averag%"
echo "Done"

It is bad design to ask up-front how many papers to grade. Just read inputs until there are no more. Then report the average.

Super easy just create a loop to ask for a grade or finished imputing then calculate average and quit

It is bad design to ask up-front how many papers to grade. Just read inputs until there are no more. Then report the average.

Here are some hints that might point you in the right direction.
Check the bash man page on while loops, the read builtin, and evaluating math expressions with the $((...)) construct.
For another approach, you might also look into for loops, the $(...) construct and the man page for the seq command.
That should give you some pieces to the puzzle. Good luck!
