# operator<<,>>(std::extreme_value_distribution)

From cppreference.com
< cpp‎ | numeric‎ | random‎ | extreme value distribution

[edit template]

template< class CharT, class Traits, class ResultType > std::basic_ostream<CharT,Traits>& operator<<( std::basic_ostream<CharT,Traits>& ost, const extreme_value_distribution& d ); | (1) |
template< class CharT, class Traits, class ResultType > std::basic_istream<CharT,Traits>& operator>>( std::basic_istream<CharT,Traits>& ist, extreme_value_distribution& d ); | (2) |

Performs stream input and output operations on pseudo-random number distribution `d`.

1) Writes a textual representation of the distribution parameters and internal state to `ost` as textual representation. The formatting flags and fill character of `ost` are unchanged.
2) Restores the distribution parameters and internal state with data read from `ist`. The formatting flags of `ist` are unchanged. The data must have been written using a stream with the same locale, `CharT` and `Traits` template parameters, otherwise the behavior is undefined. If bad input is encountered, ist.setstate(std::ios::failbit) is called, which may throw std::ios_base::failure. `d` is unchanged in that case.

### [edit] Parameters

ost | - | output stream to insert the data to
ist | - | input stream to extract the data from
d | - | pseudo-random number distribution

### [edit] Return value

1) `ost`
2) `ist`

### [edit] Exceptions

1) (none)
2) may throw std::ios_base::failure on bad input.
