Javascript math parser library

Question

Is there a good math parser in Javascript? I want to be able to parse something like:

LOG(3.14)+5^2+POW(2,LN(X*2,Y))

Thanks,

Answer 1

Here is a brand new initiative:

http://mathjs.org

Comes with an extensive and easy to use parser which also supports assignment and usage of variables and functions like in your example expression.

Answer 2

Use this one. It defined an "operator" object that lets you define your own operators.

Warning: it uses with . If you don't know why that's dangerous, find out before using this code in anything critical. Alternately, you could just re-write it without with .

Answer 3

Try nerdamer

 var result = nerdamer('log(3.14)+5^2+2^(log(X*2)/log(Y))').evaluate(); document.getElementById('text').innerHTML = result.text(); 

 <script src="http://nerdamer.com/js/nerdamer.core.js"></script> <div id="text"></div> 

Answer 4

I know it's an old question, but I found it by chance and I have something to help . Not as complete as mathjs, but useful and fast.
