( [id://3333]=superdoc: print w/replies, xml ) Need Help??
The problem is pretty simple, as others have stated and is due to the rounding off of floating point numbers.

The real problem is however, that this is a Very Frequently Asked Question and as such, should be answered in the FAQ.

Of course the question in perlfaq4:

perldoc -q Why am I getting long decimals (eg, 19.9499999999999) inste +ad of the numbers I should be getting (eg, 19.95)?
in essence answers this question, but it could be indexed with a different heading, something like:
Why don't my floating point numbers equal each other?

Title:
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 How to display code and escape characters are good places to start.
