Implements the compound assignment operators for complex arithmetic and for mixed complex/scalar arithmetic. Scalar arguments are treated as complex numbers with the real part equal to the argument and the imaginary part set to zero.

1,5) Adds other to *this.

2,6) Subtracts other from *this.

3,7) Multiplies *this by other.

4,8) Divides *this by other.

Parameters

other

-

a complex or scalar value of matching type (float, double, long double)

Return value

*this
