in reply to Improve my lookup script

You can use CPAN module, such as List::BinarySearch instead of writing code yourself.

Also, instead of using min and max you could use $array[0] and $array[-1] - the list is sorted.

Also, as far I can see, you check if value is out of bounds every time loop passes. You can move this check outside loop.

    Indeed all very good points!

    Thanks for pointing me to List::BinarySearch.

     bsearch_num_pos($lookup, @array) gives me a grip to handle further calculations.
