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.

[edit] Parameters

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

[edit] Return value

*this
