I am looking for a module that would let me do file size arithmetic from human readable sizes: add( "1 Gb", "500 Mb") would give me "1.5 Gb", add( "753 Mb", "50 Kb") would still give me "753 Mb".

I have searched CPAN and the Monastery, but didn't find anything. Is there such a module, or at least a combination of 2 modules, one that goes from human readable numbers to regular numbers, and conversely one that would go from regular numbers to readable.

Number::Format comes close, but it doesn't grok the 'G' suffix (and actually understands only K/M instead of Kb and Mb, although I can deal with that).

Is there any module that I have overlooked that could help me? Or do I need to patch Number::Format (there is a patch in the module's RT queue), which I'd rather avoid (the module on the production machine might one day be upgraded from CPAN and the patch potentially lost).

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).
Want more info? How to link or How to display code and escape characters are good places to start.


No such thing as a small change
