( #3333=superdoc: print w/replies, xml ) Need Help??

For the record, I did try this as well, but it didn't help my Monday morning mind narrow anything down. Specifically, I found the same three differences. The binary representations didn't change between the time I read the values in and the time I compared them.

First two lines are reading files in from Excel sheets, second two are later in the script when the difference is found. I didn't include all three differences here, since they're all the same scenario. Different values read in from the files, no change to those values for the comparison:

read var_f in from change file: 10011100010100111000101110010000100001 +01000001010110011000000010 read var_f in from range file : 10101100010100111000101110010000100001 +01000001010110011000000010 var_f value in change hash : 10011100010100111000101110010000100001 +01000001010110011000000010 var_f value in range hash : 10101100010100111000101110010000100001 +01000001010110011000000010

I'm not familiar enough with floating point representation to say what the difference is (it's been years since I had to convert a binary to float, and unfortunately need to do actual work this morning rather than brush up on the process). I think this is a difference in exponents, but that wouldn't make a lot of sense to me with the rest of the binary value being identical.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
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 or How to display code and escape characters are good places to start.
