Javascript Easier way to format numbers

Question

I m trying to format various numbers on my page   These numbers either represent a price  a change in price  or a percentage   I know Javascript has functions to limit the number of decimal places  but is there any support for other types of formatting  such as grouping numbers with commas  controlling whether or not the   - is shown  etc   Here s what I have so far   var FORMATTER         price         function value    return       value toFixed 2          pricePer      function value    return  value   100  toFixed 2                priceChg      function value    return  value  gt   0          -           Math abs value  toFixed 2          It works OK  but it d like to add commas to the  price  formatter  and you can see that there s a hack in the  priceChg  formatter where I try to move the   - sign in front of the     sign   Basically  I m hoping there is some library out there  jQuery is OK  that emulates Java s DecimalFormat class

Also try dojo number which has built-in localization support   It is a much closer analog to Java s NumberFormat DecimalFormat

There s the NUMBERFORMATTER jQuery plugin  details below   https   code google com p jquery-numberformatter   From the above link      This plugin is a NumberFormatter   plugin  Number formatting is likely   familiar to anyone who s worked with   server-side code like Java or PHP and   who has worked with   internationalization    EDIT  Replaced the link with a more direct one

No  there is no built-in support for number formatting  but googling will turn up loads of code snippets that will do this for you   EDIT  I missed the last sentence of your post  Try http   code google com p jquery-utils wiki StringFormat for a jQuery solution
