Original Post
I've written emulation for quadruple precision floats (IEEE-754-2008 binary128) in C++ and inline assembler, with a managed wrapper (for .Net languages). I understand the usefulness for this is very narrow, but wanted to share it anyway.
The reason I made this (for my own use) is that it has enough precision to represent each micrometer of the width of our observable universe. I've also included Log, Ln, Exp, Pow, Sin, Cos, Tan, ASin, ACos, ATan, ATan2, Ceiling, Floor, Round, Truncate, and Fraction. It also has Pi and E to full quadruple precision.
