This code definitely looks questionable: __guess += max((int)__builtin_log10(__builtin_abs(__v)) / 2, 1); So in this case, most likely the author of the above code thought __builtin_abs was type generic rather than takes an integer type. The reason why I say that is because below we have: if (!__builtin_signbit(__v)) Most likely __builtin_abs(__v) should be replaced with `(__builtin_signbit(__v) ? -__v : __v)` (which does get optimized to just `ABS_EXPR` internally.
