complex& operator-=(const complex& rhs);
complex& operator-=(const T& rhs);
The first member function replaces the stored real and imaginary parts with those corresponding to the complex
difference of *this
and rhs
. It then returns *this
.
The second member function subtracts rhs
from the stored real part. It then returns *this
.
In this implementation, if a translator does not support member template functions, the template:
template<class U>
complex& operator-=(const complex<U>& rhs);
is replaced by:
complex& operator-=(const complex& rhs);
