numbro.js provides functions to format numbers and currency amounts.
It uses its own format specification language, which is defined by example. See the numbro.js docs for examples of what's possible.
At the moment, numbro keeps the language setting in a global variable, which makes it difficult to provide formatting functions which take a language/culture parameter without affecting other calls to numbro.
To set the language/culture for a question, call numbro.culture in the question preamble, e.g. numbro.culture('nb-NO').
