Quadmath


Dear GCC developers,

I would just like to say a massive thanks for the work that led to the development of the Quadmath libraries. I have been doing  my own research project with Matlab and last Christmas I ran out of numbers. I have developed a set of formulae that relate Planck’s constant, the speed of light and the fundamental constants of electromagnetism, Z0, epsilon0 and mew0 but I was stuck with only 1 significant figures. As a result of installing gcc on my Cygwin installation and finding the quadmath libraries I have been able to prove agreement of my formulae in terms of reciprocal self-consistency to 93 significant digits. I was previously stuck with double precision based on 32 bit assumed architecture that gave me 15 decimal digits. I know have quadmath on my 64 bit machine giving me way more than I ever expected and the numbers seems to stack up. I hope I will be able to either publish something in the future, or make some money such that I can make a donation. In any event it has been a lot of fun. Once again, thank you.

Andy
