UNIX for Dummies Questions & Answers

Hi there,

I am totally new to Unix, I am trying to work out the percentage between two values in a ksh shell script and assign the result to a variable.

Value1=577
Values2=244

So the calculation would be as follows:
((Value1 - Value2) / Value1) * 100

How would I be able to achieve this calulation in a ksh shell script?

I have heard that expr can't handle non-integer values and since the above calculation will result in a non-integer value, what other options would I have?

Any help would be greatly appreciated.

Thank you

One way:

Code:

echo "$Value1" "$Value2" | awk '{print ($1-$2)/$1*100}'

Thank you very much, it works like a bomb
