Detailed Description
binary-compatible std::complex faster implementation
For some reason, the compilers are not inlining std::complex operations, resulting in way slower code. This template is binary-compatible so it can be reinterpreted as to one another and its operations can be inlined easily. This results in much faster code for FFT for instance.
