Detailed Description

template<typename _Tp>
class 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.
