For math/test-float-j0 and math/test-float-y0, it appears those inputs give an error larger than 9 ulps for some directed rounding modes. For other failures, it appears those inputs, when converted to other formats, also give errors larger than 9 ulps. Should I remove those inputs from auto-libm-test-in? Best regards, Paul
