Parameter

left
Bilangan kompleks atau objek dari jenis parameternya yang akan diuji untuk ketidaksamaan.

operator==

Pengujian untuk kesetaraan antara dua bilangan kompleks, satu atau keduanya mungkin termasuk dalam subset jenis untuk bagian nyata dan imajiner.

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);

Parameter

left
Bilangan kompleks atau objek dari jenis parameternya yang akan diuji untuk ketidaksamaan.

right
Bilangan kompleks atau objek dari jenis parameternya yang akan diuji untuk ketidaksamaan.

Tampilkan Nilai

true jika angkanya sama; false jika angka tidak sama.

Keterangan

Dua bilangan kompleks sama jika dan hanya jika bagian aslinya sama dan bagian imajinernya sama. Jika tidak, mereka tidak sama.

Operasi kelebihan beban sehingga pengujian perbandingan dapat dijalankan tanpa konversi data ke format tertentu.
