--- Comment #1 from Steve Kargl <ka...@freebsd.org> --- All, Paul supplied me with his test framework. Exhaustive testing of the float implementations in round-to-nearest yields Checking cospi MPFR library: 4.2.0-p9 MPFR header: 4.2.0-p9 (based on 4.2.0) Checking function cospif with MPFR_RNDN libm wrong by up to 5.01e-01 ulp(s) [1] for x=0x1.112f4ep-4 cospi gives 0x1.f4cd4cp-1 mpfr_cospi gives 0x1.f4cd4ap-1 Total: errors=110478 (0.00%) errors2=0 maxerr=5.01e-01 ulp(s) Checking sinpi MPFR library: 4.2.0-p9 MPFR header: 4.2.0-p9 (based on 4.2.0) Checking function sinpif with MPFR_RNDN libm wrong by up to 7.50e-01 ulp(s) [1] for x=0x1.72681p-129 sinpi gives 0x1.22eaa8p-127 mpfr_sinpi gives 0x1.22eaa4p-127 Total: errors=4614478 (0.11%) errors2=0 maxerr=7.50e-01 ulp(s) Checking tanpi MPFR library: 4.2.0-p9 MPFR header: 4.2.0-p9 (based on 4.2.0) Checking function tanpif with MPFR_RNDN libm wrong by up to 8.00e-01 ulp(s) [1] for x=0x1.4442bep-5 tanpi gives 0x1.fffd42p-4 mpfr_tanpi gives 0x1.fffd44p-4 Total: errors=63422266 (1.48%) errors2=0 maxerr=8.00e-01 ulp(s) -- You are receiving this mail because: You are the assignee for the bug.
