However, some builds end up using FMA so you get (normally) improved accuracy. Others compute at the next highest accuracy than declared.
And some people, sadly myself included, rely on an FMA to obtain better accuracy with simpler coding in some of their research. I have not seen that (less than wise) approach in LIBM/GLIBC although once FMA becomes the norm for architectures, we may start to see that.
My aim is to have all machines in my universe with FMA by the end of 2019. Regards - Damian Pacific Engineering Systems International, 277-279 Broadway, Glebe NSW 2037 Ph:+61-2-8571-0847 ..
