163 | facilitate the common operations with sizes in bytes. Many projects need to | |

165 | them need to deal with the same issues like: | |

167 | @itemize | |
168 | @item How to get a human-readable string for the given size? | |
169 | @item How to store the given size so that no significant information is lost? | |
170 | @item If we store the size in bytes, what if the given size gets over the | |
171 | MAXUINT64 value? | |
172 | @item How to interpret sizes entered by users according to their locale and | |
173 | typing conventions? | |
174 | @item How to deal with the decimal/binary units (MB versus MiB) ambiguity? | |
