I'm not entirely sure what you're asking for here. Your code looks okay, but I really wonder about the parts that are commented out -- the net effect is that I'm not sure what you're trying to do.

If your question involves reformatting the data that comes out of the second query (for averages), I'm not sure why you need to do this; if a scalar variable is assigned a "string" value like "9.9871239340160043e-005", and then use that variable in an arithmetic operation, it just works as a number, and you don't need to do any explicit conversion yourself.

But in general, if you're wondering how to do things to values as you move them through a hash slice assignment, that is what "map" is for:

@avgsHash{ @cols } = map { some_conversion($_) } @avgs;

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
