Yes - I think this is generally considered to be a perl bug. (That's how I, at least, regard it.)
If perl's nvtype is 'double', perl will print floating point values rounded to 15 decimal digits - whereas the correct thing would be to round them to 17 decimal digits.
Hence the surprising result that you see.

Perl will correctly tell you that 3336.0 != 3335.9999999999995, yet will print both of those values identically (as 3336) ... which is rather absurd.

If you want to see the values rounded to 17 decimal digits then the best solution currently is to printf() 17 decimal digits - eg:

printf "%.16e\n", 3335.9999999999995;

• 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).
