v3 v5 1 This is a doctest error on Solaris SPARC introduced by #12557:1 This is a doctest error on Solaris SPARC and FreeBSD introduced by #12557: 2 2 {{{ 3 3 sage -t --long -force_lib devel/sage/sage/rings/real_double.pyx … … 12 12 }}} 13 13 14 It turns out that the bug is actually in the `ulp()` method which returns a value which is a factor 2 too small. Since in all other systems except SPARCthe RDF `log()` method is accurate up to 0.5 ulp, the tests for #12557 passed.14 It turns out that the bug is actually in the `ulp()` method which returns a value which is a factor 2 too small.
