LP Simplex algorithm in C++
I need the robust C++ source code of the simplex algorithm (is a popular algorithm for numerical solution of the linear programming problem). 

Please, no links to wikipedia. I need good source code in C++, using templates, clear user-friendly names and work very well. 

Preferably algorithm must check the unstable floating-point calculation.
