Subject: [musl] musl 1.2.4
Date: Wed, 16 Aug 2023 16:39:25 +0200 [thread overview]
Message-ID: <p9u0bkf73vc2.fsf@coriandre.loria.fr> (raw)
Hi,
while updating our comparison of mathematical functions with Musl 1.2.4,
I noticed the following two issues with acoshl and exp10l in double extended
precision:
zimmerma@coriandre:~/svn/tbd/20/src/binary80$ VERBOSE=-v ./doit.musl acosh 1000
Checking acosh with musl-1.2.4
Using seed 2804715
Using 6 threads
NEW acosh 0 -1 -0x6.e2368c0ed74e5698p+16l [-nan] [inf] inf inf
libm gives -0x4.b4d6a621e8e631f8p+0l
mpfr gives nanl
zimmerma@coriandre:~/svn/tbd/20/src/binary80$ VERBOSE=-v ./doit.musl exp10 1000
Checking exp10 with musl-1.2.4
Using seed 2807610
Using 6 threads
exp10 0 -1 0x2.68826a13ef3fde64p+16376l [-nan] [inf] inf inf
libm gives nanl
mpfr gives infl
These issues were already present in 1.2.2 at least, but only detected
recently by our program.
Best regards,
Paul
