java pattern filter
<p>i need created java pattern to filter data, like 13.6Gb, 12MB,15.5Kb
I use those code</p>

<pre><code>  Pattern   p   =   Pattern.compile("(\\d+)(\\w+)"); 
  Matcher   m   =   p.matcher(content);
  String   num_letter   =   m.group(1); 
  String    union  =   m.group(2); 
</code></pre>

<p>but it can't detect decimal number, so how to modify this pattern</p>
