Sure. There should be a gcc flag to make "long double" become quadruple precision.

The thing is, my first programming language was x86 assembler and the fpu was the funniest part. Spent weeks as a teenager writing almost pure 8087 code. I have a lot of emotional investment in that tiny rolling stack of extended precision floats.



How is "quad floating point" implemented on x86? Is it software emulation?
