operator!= (<complex>)

2 個の複雑な間の非等値のテスト、1 ページまたは実際という部分の型のサブセットに属する場合があります。

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
   );

パラメーター

• _Left
  非等値をテストするパラメーターの型または複合型のオブジェクト。

• _Right
  非等値をテストするパラメーターの型または複合型のオブジェクト。

戻り値

数がではないtrue ; 数が等しい場合 false。

解説

2 個の複合型は、の実数部がある場合にのみ、まったく等しい、架空の部分は同じです。それ以外の場合は等しくありません。

比較操作はテストが特定の形式のデータへの変換なしで実行できるようにオーバーロードされます。

使用例

// complex_op_NE.cpp
// compile with: /EHsc
#include <complex>
#include <iostream>

int main( )
{
   using namespace std;
   double pi = 3.14159265359;

   // Example of the first member function
   // type complex<double> compared with type complex<double>
   complex <double> cl1 ( polar (3.0 , pi / 6 ) );
   complex <double> cr1a ( polar (3.0 , pi /6 ) );
   complex <double> cr1b ( polar (2.0 , pi / 3 ) );

   cout << "The left-side complex number is cl1 = " << cl1 << endl;
   cout << "The 1st right-side complex number is cr1a = " << cr1a << endl;

   if ( cl1 != cr1a )
      cout << "The complex numbers cl1 & cr1a are not equal." << endl;
   else

   else
      cout << "The complex numbers cl1 & cr1b are equal." << endl;
   cout << endl;

   // Example of the second member function
   // type complex<int> compared with type int
   complex <int> cl2a ( 3 , 4 );
   complex <int> cl2b ( 5 ,0 );
   int cr2a =3;
   int cr2b =5;

   cout << "The 1st left-side complex number is cl2a = " << cl2a << endl;
   cout << "The 1st right-side complex number is cr2a = " << cr2a << endl;
   if ( cl2a != cr2a )
      cout << "The complex numbers cl2a & cr2a are not equal." << endl;
   else
      cout << "The complex numbers cl2a & cr2a are equal." << endl;

   cout << "The 2nd left-side complex number is cl2b = " << cl2b << endl;
   cout << "The 2nd right-side complex number is cr2b = " << cr2b << endl;
   if ( cl2b != cr2b )
      cout << "The complex numbers cl2b & cr2b are not equal." << endl;
   else
      cout << "The complex numbers cl2b & cr2b are equal." << endl;
   cout << endl;

   // Example of the third member function
   // type double compared with type complex<double>
   double cl3a =3;
   double cl3b =5;
   complex <double> cr3a ( 3 , 4 );
   complex <double> cr3b ( 5 ,0 );

   cout << "The 1st left-side complex number is cl3a = " << cl3a << endl;
   cout << "The 1st right-side complex number is cr3a = " << cr3a << endl;
   if ( cl3a != cr3a )
      cout << "The complex numbers cl3a & cr3a are not equal." << endl;
   else
      cout << "The complex numbers cl3a & cr3a are equal." << endl;

   cout << "The 2nd left-side complex number is cl3b = " << cl3b << endl;
   cout << "The 2nd right-side complex number is cr3b = " << cr3b << endl;
   if ( cl3b != cr3b )
      cout << "The complex numbers cl3b & cr3b are not equal." << endl;
   else
      cout << "The complex numbers cl3b & cr3b are equal." << endl;
   cout << endl;
