I wonder how this should be handled.
Example: (poor implementation)
template<typename T>
inline T Limit (T x) {
return (x == T(0)) ? T(0) : x / abs (x);
}
It would be better to test abs(x) < epsilon where epsilon might be
numeric_limits<T>::epsilon, or something to that effect.
But what if T is complex? One possibility is to specialize Limit for
the complex case. But is a more elegant approach possible? Should
complex have it's own numeric_limits?
