operator + abstract method
Returns a Complex
whose value is
(this + addend)
.
Uses the definitional formula
(a + bi) + (c + di) = (a+c) + (b+d)i
If either this
or addend
has a NaN
value in
either part, NaN
is returned; otherwise Infinite
and nan values are returned in the parts of the result
according to the rules for double arithmetic.
Implementation
Complex operator +(Object addend);
