Detailed Description

template<typename _Tp>
struct std::complex< _Tp >

Template to represent complex numbers.

Specializations for float, double, and long double are part of the library. Results with any other type are not guaranteed.

Parameters
TpType of real and imaginary values.

Member Typedef Documentation

◆ value_type

template<typename _Tp >
typedef _Tp std::complex< _Tp >::value_type

Value typedef.

Definition at line 125 of file complex.

Constructor & Destructor Documentation

◆ complex() [1/2]

template<typename _Tp >
constexpr std::complex< _Tp >::complex ( const _Tp &  __r = _Tp(),
const _Tp &  __i = _Tp() 
)
inline

Default constructor. First parameter is x, second parameter is y. Unspecified parameters default to 0.

Definition at line 129 of file complex.

◆ complex() [2/2]

template<typename _Tp >
template<typename _Up >
constexpr std::complex< _Tp >::complex ( const complex< _Up > &  __z)
inline

Converting constructor.

Definition at line 139 of file complex.

Member Function Documentation

◆ operator+=()

template<typename _Tp >
complex<_Tp>& std::complex< _Tp >::operator+= ( const _Tp &  __t)
inline

Add a scalar to this complex number.

Definition at line 184 of file complex.

◆ operator-=()

template<typename _Tp >
complex<_Tp>& std::complex< _Tp >::operator-= ( const _Tp &  __t)
inline

Subtract a scalar from this complex number.
