26.4 Complex numbers [complex.numbers]

26.4.6 Member operators [complex.member.ops]

constexpr complex& operator+=(const T& rhs);
Effects: Adds the scalar value rhs to the real part of the complex value *this and stores the result in the real part of *this, leaving the imaginary part unchanged.
Returns: *this.
constexpr complex& operator-=(const T& rhs);
Effects: Subtracts the scalar value rhs from the real part of the complex value *this and stores the result in the real part of *this, leaving the imaginary part unchanged.
Returns: *this.
constexpr complex& operator*=(const T& rhs);
Effects: Multiplies the scalar value rhs by the complex value *this and stores the result in *this.
Returns: *this.
constexpr complex& operator/=(const T& rhs);
Effects: Divides the scalar value rhs into the complex value *this and stores the result in *this.
Returns: *this.
template<class X> constexpr complex& operator+=(const complex<X>& rhs);
Effects: Adds the complex value rhs to the complex value *this and stores the sum in *this.
Returns: *this.
template<class X> constexpr complex& operator-=(const complex<X>& rhs);
Effects: Subtracts the complex value rhs from the complex value *this and stores the difference in *this.
Returns: *this.
template<class X> constexpr complex& operator*=(const complex<X>& rhs);
Effects: Multiplies the complex value rhs by the complex value *this and stores the product in *this.
Returns: *this.
template<class X> constexpr complex& operator/=(const complex<X>& rhs);
Effects: Divides the complex value rhs into the complex value *this and stores the quotient in *this.
Returns: *this.
