Which C++ math parsers can you recommend?

Question

Mathematics

Hello!
Of the required:

• operations: +, -, *, /, ^.
  
• functions: sin, cos.
  
• selection of several variables, for example sin(a*x + b).
  

It is desirable to have the mod operator, the abs function and the ability to set values ​​for constants (for example, pi).
At the time of writing, a good list of parsers is provided on the Math Parser Benchmark Project page .
I would like to know what parsers people in the habra community use.
