digit decimal; ten's digit,decimal digit; tensdigit,decimal number

Computers need numerical value change between binary system,octal system and decimal system The fortran77 is used in the programming to perform the numerical value converting.

计算机需要数制转换,计算机内部使用二进制,二进制八进制十进制之间的数制转换,FORTRAN77编制,围绕二进制与小数,完成二进制八进制十进制之间的数制转换。

In this paper, the authors described the decimal system encryption based on AES and its implementation in detail, and discussed a kind of encryption principle suitable for trustless channel.

详细描述了基于AES的十进制加密算法的实现过程和一种适合于不可靠信道(预付费系统与终端之间的通信实现非接触无介质代码传送)的加密算法实现原理。
