jquery-numberformatter
This plugin is a number formatting and parsing plugin for jQuery. Number formatting is likely familiar to anyone who's worked with server-side code like Java or PHP and who has worked with internationalization. People who aren't stuck in the US-centric frame of mind can quickly point out that people in other parts of the world don't format their numbers in the same way as Americans. For example, a number that we would write in the US as "1,250,500.75" would be written differently in different countries: "1.250.500,75" in Germany, "1 250 500,75" in France, and "1'250'500.75" in Switzerland, and "125,0500.75" in Japan. The number is exactly the same, but it's just written using a different format when presented to users of the web application.
