Division by zero attempted error during linear conversion of values between 0.25 to 1
I want to implement the below formula with awk oneliner
I want to pass the value of old_min and old_min as variable. Here is what I did for this
Then I run the command, which gives the error message
Then I tried simply which worked fine
but I need to assign $old_min and $old_max dynamically as my script.sh run it inside the loop. Thanks

new=$(($old/300))

How will i get the fraction values ?
