在 C++ 中评估数学表达式的最佳方法是什么?
问题描述：
例如，评估任何自定义数学表达式的最佳方法是什么
What is the best way to evaluate any custom math expression, for example
3+sqrt(5)+pow(3)+log(5)
我知道将 Python 嵌入 C++ 可以做到这一点；有没有更好的办法?
I know that embedding Python into C++ can do that; is there any better way?
谢谢！

Boost.Spirit 是一个 C++ 解析器库.
Boost.Spirit is a C++ parser library.
示例:
- in its distribution: classic version and current version (look for "calc");
- on Rosetta wiki;
- some applications using it.
