Are you concerned about accuracy or precision? In general, accuracy is "how close to the correct value is my answer", while precision is "how many significant digits does my answer contain."
What you are describing is precision - and as someone else mentioned, bignum could be your friend. However, once you start manipulating high precision values, you need to make sure your numerical methods do not reduce your accuracy. In the dim, dark past, I did an honours-level university applied math subject that dealt with how to structure calculations so that numerical rounding errors did not accumulate and destroy your accuracy. Sadly, I have forgotten much of it!

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).
