operator!= (<complex>)

测试对于两个复数之间的不等，或两者可以属于类型的子集物理和虚构的指针。

template<class Type>
   bool operator!=(
      const complex<Type>& _Left,
      const complex<Type>& _Right
   );
template<class Type>
   bool operator!=(
      const complex<Type>& _Left,
      const Type& _Right
   );
template<class Type>
   bool operator!=(
      const Type& _Left,
      const complex<Type>& _Right
   );

参数

• _Left
  对于不相等要测试的参数类型的复数或对象。

• _Right
  对于不相等要测试的参数类型的复数或对象。

返回值

true，如果数字不相等; false，如果数字相等。

备注

两个复数相等，则，因此，只有在其实部相等，并且它们的虚拟部分相等。否则为不相等。

重载操作，以便比较的测试方法中执行，而无需数据转换为特定格式。
