Subject: [musl] issue with sinhf
Date: Fri, 05 Feb 2021 09:01:09 +0100 [thread overview]
Message-ID: <mweehvose2.fsf@tomate.loria.fr> (raw)
Hi,
a similar issue happens with sinhf:
$ cat test_sinh_musl.c
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
int
main ()
{
float x = 0x1.62e4p+6;
float y = sinhf (x);
printf ("x=%a y=%a\n", x, y);
}
With GNU libc:
$ gcc -fno-builtin test_sinh_musl.c -lm
$ ./a.out
x=0x1.62e4p+6 y=0x1.ffe808p+126
With musl-1.2.2:
$ gcc -fno-builtin test_sinh_musl.c $FILES
$ ./a.out
x=0x1.62e4p+6 y=-nan
Here we get NaN whereas the result is perfectly valid.
Best regards,
Paul
