The Auxiliary program program created by C++ language for the input and output of these numbers. The calculation function of double-double and quad-double precision can be given to C++ language which does not usually have double-double and quad-double precision by using this library. By using this library, not only can C ++ languages that normally do not have double-double or quad-double precision have double-double or quad-double arithmetic functions, but also double-double and quad-complex complex arithmetic operations. Using these libraries, we ran programs of simultaneous linear equations and real Fourier transform of radix 8 to evaluate these performance. By using this library, existing C ++ language programs can be easily converted to double-double or quad-double precision programs. Many programs can be calculated with high accuracy.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告ハイパフォーマンスコンピューティング（HPC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2021-05-07","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"6","bibliographicVolumeNumber":"2021-HPC-179"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":211056,"links":{}}
