Hi Suman, I don't really understand the question. Bash printf prints data to standard output. I can't see how you can use Bash's printf to compare floating point values. Sorry. Confused. (Bash only supports integer arithmetic - which we'll cover shortly Cheers MichaelW

Hi, If you are running the standard Ubuntu/Bash/Gnu-Shell-Tools set up, having the .sh on the end of file name should not matter. Instead you need the #!/usr/bin/env bash as the first line. (To my taste, having .sh at the end of Shell script is misleading unless you intend to use sh (ie the original Shell, of which Bash is a derivative.). Cheers MichaelW

Thanks for clarifying Michael. I've gotten ahead of myself with the textbook ;-). Will find a new solution!

Hi, Thank you for the response, I mean I can convert it into int first without decimal like printf "%.0f", variablename and store it in other variable and then compare. just let me know if this can be valid

Hi, This makes no sense to me. If you are able to capture a floating point real in this way (outside of Awk), you will comparing strings, which is not a good idea if you actually are working with numbers (see the discussion on arithmetic versus string comparisons). Cheers MichaelW
