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,
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.
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
.
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>
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.
