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
