Floating point numbers simply cannot be stored precisely on a computer.
I know what you mean, but it's not what you said. {grin}
Insert Some at the beginning of that sentence to make it true. I can certainly represent "0.5" precisely in IEEE floating point. And actually, it might make more
sense to say:
Most fixed-decimal values cannot be represented precisely as binary floating-point
numbers, no matter what the precision, because 1/10th is an infinite repeating fraction in binary. Unless the number is an integer divided by a power of two, you'll get some sort of truncation error.

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).
