--- Comment #4 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-04-23 20:26:47 UTC --- I'm following with interest the numerical analysis side of the discussion, but I have to add that, *as a libstc++-v3 proper* issue, as mentioned by Richard, the issue is moot, because in currently active release branches either the library uses a front-end builtin (__builtin_powi*) or just pow unconditionally (in C++0x mode). In other terms, *minimal* open-coding in the library for these functions (and we mean to stick to this general design choice, AFAIK)
