Update.
2004-02-12 Jakub Jelinek <jakub@redhat.com> * math/libm-test.inc (lrint_test): Add new test. (llrint_test, lround_test, llround_test): Likewise. * sysdeps/ieee754/ldbl-128/s_lroundl.c (__lroundl): Fix special case with result taking up 48 bits. * sysdeps/ieee754/ldbl-128/s_lrintl.c (__lrintl): Likewise. * sysdeps/ieee754/ldbl-128/s_llroundl.c (__llroundl): Likewise. * sysdeps/ieee754/ldbl-96/s_llrintl.c (__llrintl): Fix special case with result taking up 31 bits.
