Interesting stuff for folks who have a use for high precision maths. We have a member here Ray Filiatrault who has a background in maths and I remember long ago Ray mentioning a technique of fixed point maths that could do unusual things.

as long as masm64 sdk started,I have wanted to try out if 64bit version fixed point and time it vs real8's

but I prefer the real4's and real8's flexibility and together with SIMD its fast

scalar it seems like its going to be a race between conversion between float/ints using floats vs extra bitshifting when using fixed points
