Comments on: Class::Measure 0.04 Released http://blog.bluefeet.net/2009/06/classmeasure-0-04-released/ Yet another Perl Hacker weblog Wed, 03 Feb 2010 13:07:54 -0500 http://wordpress.org/?v=2.8.4 hourly 1 By: bluefeet http://blog.bluefeet.net/2009/06/classmeasure-0-04-released/comment-page-1/#comment-8 bluefeet Sun, 28 Jun 2009 17:29:41 +0000 http://blog.bluefeet.net/?p=67#comment-8 Well, measure is the word we use to denote the recording of the size/weight/etc of things. We measure them, and record the value. This module is used to create objects that represent these measurements, and allows you to hide away the conversion of measurements from one unit to another. Yes, the numbers are objects. length(), for example, returns an object of type Class::Measure::Length. The objects support operator overloading so you can do things like: my $two_inches = 2 * lengt(1, 'inch'); Looking at my perldoc of Class::Measure and Class::Measure::Length I am now realizing that it is greatly deficient in describing what it actually does. :) I'll work on fixing that. Let me know if you have any other questions, Aran Well, measure is the word we use to denote the recording of the size/weight/etc of things. We measure them, and record the value.

I am asking because I recently looked for a package doing unit-sensitive computations and "Measure" would not have made me realize what the package does. I also wonder what the 'Class'y side of the package is. Are the numbers objects? What has this to do with “measure”ment?
