But, actually, I don't think there are any inconsistencis here: the C++03 standard has no notion of -0.0 and, I maintain, the return value of sqrt(-1.0, -0.0) is undefined in C++03. Moreover, the value which we are currently (in GCC 4.x) returning, is consistent with C99 and LIA-3, and that seems a good QoI to me. Really, after all, I think everything is fine, for now at least (in principle C++0x may decide to be inconsistent with C99 and LIA-3 ;) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28406
