pow

Karmaşık bir sayıyı başka bir sayının kuvveti olan temel yükselterek elde edilen karmaşık sayı olarak değerlendirilir.

template<class Type>
   complex<Type> pow(
      const complex<Type>& _Base, 
      int _Power
   );
template<class Type>
   complex<Type> pow(
      const complex<Type>& _Base,
      const Type& _Power
   );
template<class Type>
   complex<Type> pow(
      const complex<Type>& _Base,
      const complex<Type>& _Power
   );
template<class Type>
   complex<Type> pow(
      const Type& _Base,
      const complex<Type>& _Power
   );

Parametreler

• _Base
  Karmaşık sayı veya üye işlevi tarafından üssü için temel olan karmaşık sayı için parametre türü numarası.

• _Power
  Tamsayı veya karmaşık sayı veya esas üye işlev için yükseltilmiş olması için güç olan karmaşık sayı için parametre türü numarası.

Dönüş Değeri

Belirtilen güç için belirtilen taban yükselterek elde edilen karmaşık sayı.

Notlar

İşlevler her etkili bir şekilde her iki işlenen dönüş türüne dönüştürmek ve dönüştürülmüş dönmek sol gücüne sağ.

Şube Kes negatif gerçek ekseni boyunca olur.
