## 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

  Tp | Type 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.

## operator-=()

template<typename _Tp>

complex<_Tp>& std::complex< _Tp >::operator-= | ( | const _Tp & | __t | ) |

inline

Subtract a scalar from this complex number.
