双字

双字正是根据其名称是两个字.于是双重词量为32位元.双字也可以分为高阶与低阶词字,4字节,8换档等等

这样的双重代表各种不同的文字资料.也许有以下方面:

 

  • 一个双字签名射程04,294,967,295,
  • 署名双字范围-2,147,483,648到2,147,483,647,
  • 32位浮点值
  • 或任何其他资料,需要32位元或以下.

octal数制

octal流行的一些旧电脑系统,但极少使用.但是我们将把octal制度只是一种理想的知识.

该系统是基于octal二进制为3比特边界.该系统采用数字基地octal包含8只通过7位0.这样将使其他数字无效octal人数多少.
