Thanks for the link, but thats not really what I'm looking for. I'd like to
know 'how' to convert a binary number to a correctly rouned double float to
implement this directly for the GMP-library without using the inefficient
indirection with MPFR.

Isn't there any good tutorial how to do such things?
