       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
