division by zero
Hello,

I am searching for a way to calculate for example 10/100 within a shellscript and the result should be 0.1 and not just 0.

Every alternative i tried just results 0

Thank you in advance

try this in shell script

div=$(echo "scale=2; 10 / 100" | bc)

echo "$div"

It works, but the output is ".1" and not "0.1" Smilie

I can`t calculate further with ".1"
