operator+ (<complex>)
添加两个复数,或者这两者可能属于类型子集物理和虚部的集合。
template<class Type>
complex<Type> operator+(
const complex<Type>& _Left,
const complex<Type>& _Right
);
template<class Type>
complex<Type> operator+(
const complex<Type>& _Left,
const Type& _Right
);
template<class Type>
complex<Type> operator+(
const Type& _Left,
const complex<Type>& _Right
);
template<class Type>
complex<Type> operator+(
const complex<Type>& _Left
);
参数
_Left
是它的参数类型将由添加 + 操作的第一个复数或数字。_Right
是它的参数类型将由添加 + 操作的第二个复数或数字。
返回值
由两个数字值和添加类型由参数指定的复数输入。
备注
重载以便操作,简单算术操作来执行,而无需转换为特定数据的格式。 一元运算符返回 _Left.。
