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,

Here is a brand new initiative:

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