Divide by zero script

Shell Programming and Scripting

Hi,

I've been working on a few scripts and have been getting great info.
How, would I include in the below script, how I would let a user know that if they divide a SECOND number by zero, that they would get a divide by zero error? What's the easiest way of working this?

Cordially,
joe.

I think I asked this and didn't get a viable answer before. 'Trying again.

Example: If 5 / 0 -( "0" is second number), A divide by zero error warning would be included in the script.

Script:

echo "Enter a number."
read num1
echo "Enter another number."
read num2
div=$((num1 / num2))
echo "div=$div"
2

Get non-zero number

while :
do
  echo "Enter another number."
  read num2
  if [[ $num2 -eq 0 ]]; then
    echo "divide by zero, try again"
  else
    break
  fi
done
