I'm really hoping that this struct class of Christof's will work for me here because I think that I would have even a worse time trying to code an FLL in C++ since, apart from the language barrier, I'd still need to have a clearer understanding of how C is working with these structures etc.

That's OK - the latest version of CLSHeap has a fast and accurate conversion of the DOUBLE data type.
