Can't get your code to work. It dies with message:
Operation `**': no method found,
left argument in overloaded package Math::BigFloat,
right argument has no overloaded magic at test.pl line 17.
Update:
BTW It seems that using Math::BigFloat methods directly is slighly faster then relying on overloaded operations:
use Benchmark;
use Math::BigFloat;
timethese(1000, {
Methods => sub { Math::BigFloat->new(100)->fmul(Math::BigFloat->ne
+w(100)) },
Operations => sub { Math::BigFloat->new(100) * Math::BigFloat->new
+(100) },
});
bash-2.05a$ perl test.pl
Benchmark: timing 1000 iterations of Methods, Operations...
Methods: 2 wallclock secs ( 1.48 usr + 0.01 sys = 1.49 CPU) @ 67
+1.14/s (n=1000)
Operations: 1 wallclock secs ( 1.63 usr + 0.00 sys = 1.63 CPU) @ 61
+3.50/s (n=1000)

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).

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