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
