Subject: Re: operator-(const T&, const complex<T>&) vs
operator-(const complex<T>&, const complex<T>&)
I don't see how you can trigger wrong behaviour with
operator-(const complex<T> &lhs, const T &rhs):
template<typename _Tp>
inline complex<_Tp>
operator-(const complex<_Tp>& __x, const _Tp& __y)
{
complex<_Tp> __r = __x;
__r.real() -= __y;
return __r;
}
Isn't the unary operator- a necessary ingredient for the bug because it
silently changes the sign of zero?
