Original:
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.
