一个十进制的数可以用编码二进制形式来代表。
通过应用各种编码技术，字位的组合不但可以用来表示二进制数，还可以表示其他离散符号，比如十进制数字和字母表上的字母等。
By using various coding techniques, group of bits can be made to represent not only binary number but also other discrete symbols, such as decimal digits or letter of alphabet.
当然，幂和尾数都是用二进制数系统来编码，而不是十进制数系统。
Of course, both exponent and mantissa are encoded using a binary system rather than a decimal system.
