http://i-programmer.info/news/202-number-crunching/9707-better-than-floating-new-number-format-avoids-imprecision.html
http://i-programmer.info/news/202-number-crunching/9707-better-than-floating-new-number-format-avoids-imprecision.htmlIt is well known that the way computers do arithmetic isn't the same way we do arithmetic, but if you thought that IEEE 754 floating point was the last word then you need to rethink. A new format called unum saves bits in all senses of the word and promises better precision.

http://i-programmer.info/news/202-number-crunching/6811-mathjs-a-math-library-for-javascript.html
http://i-programmer.info/news/202-number-crunching/6811-mathjs-a-math-library-for-javascript.htmlWhat a language is good at depends a little on its basic syntax and semantics, but a whole lot more on what libraries are easily available. If you don't think of JavaScript as a math language then perhaps you need to meet Math.js.
