Dear Sunil,

I only find a error of 0.598 ulp, whereas the largest error for binary32
is obtained for 0x1.ec2dd8p-4 (1.73 ulp). More precisely for x=0x1.f80094p-8
glibc 2.35 returns 0x1.f8031ep-8 (x86_64, skylake). Do you get a different value?
Maybe you used different CFLAGS than the default ones?
Best regards,
Paul
