The ldbl-128ibm implementation of logl is inaccurate for arguments near 1, because when deciding whether to bypass a series expansion for log(1+z), where z = x-1, it compares the square of z rather than z itself with an epsilon value. This patch fixes that comparison, so eliminating the test failures for inaccuracy of logl in such cases. Tested for powerpc. [BZ #19351] * sysdeps/ieee754/ldbl-128ibm/e_logl.c (__ieee754_logl): When expanding log(1+z), compare z rather than its square with epsilon to determine when to avoid evaluating the expansion. |
