翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク bignum ： FOLDOC bignum /big'nuhm/ (Originally from MIT MacLISP) A {multiple-precision} computer representation for very large integers. Most computer languages provide a type of data called "integer", but such computer integers are usually limited in size; usually they must be smaller than 2^31 (2,147,483,648) or (on a bitty box) 2^15 (32,768). If you want to work with numbers larger than that, you have to use floating-point numbers, which are usually accurate to only six or seven decimal places. Computer languages that provide bignums can perform exact calculations on very large numbers, such as 1000! (the factorial of 1000, which is 1000 times 999 times 998 times ... times 2 times 1). For example, this value for 1000! was computed by the MacLISP system using bignums: 40238726007709377354370243392300398571937486421071 46325437999104299385123986290205920442084869694048 00479988610197196058631666872994808558901323829669 94459099742450408707375991882362772718873251977950 59509952 スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
