Hi,
I hope this is not off-topic for this list (Technical discussions relating
to FreeBSD).
We have updated our comparison:
https://members.loria.fr/PZimmermann/papers/accuracy.pdf
This new update includes for the first time the FreeBSD math library,
whose accuracy is quite good, except:
* single precision: the Bessel functions, lgammaf, cospif, sinpif, tanpif, powf
* double precision: the Bessel functions, lgammaf, tgammaf, cospi, sinpi,
tanpi, pow
* double-extended precision: erfcl, lgammal, tgammal, cospil, sinpil, tanpil,
powl
Some issues have already been fixed in the development version by Steve
Kargl (we used FreeBSD 13.2).
Best regards,
Paul
