Синтаксис:

 bytesize ::= zero 
            | [ sign ] intnumber
            | [ sign ] size 
                       [ size 
                         [ size
                           [ size
                             [ size
                               [ size ]
                             ]
                           ]
                         ]
                       ]
            .
 sign      ::= '-' | '+' .
 intnumber ::= digit { digit } .
 size      ::= floatnum [ suffix ] .
 floatnum  ::= intnumber [ '.' intnumber ] .
 suffix    ::=        'kb' | 'mb' | 'gb' | 'tb' | 'pb'
             | 'b'  | 'k'  | 'm'  | 'g'  | 't'  | 'p'
             .
 

Примеры:
"10" - 10 байт
"12k" - 12 килобайт
"12mb" - 12 мегабайт
"14m" - 14 мегабайт
"14.5m" - 14 мегабайт + 512 килобайт
"15m 12k" - 14 мегабайт + 12 килобайт
