日常生活中,人们一般习惯采用十进制进行计数,也就是逢十进一。例如人民币,十分为一角,十角为一元,然后是拾、百、千、万元等等。但是并非都是如此,也可以采用非十进制进行计数。例如时间,六十秒为一分,六十分为一小时,是六十进制;十二个月为一年,是十二进制。再如通常说的一打铅笔为十二支,也是十二进制;而鞋两只为一双,则是二进制,如此等等。而在电子数字计算机中,就是采用逢二进一的二进制。
In daily life, people are generally accustomed to using decimal to count, that is, every ten into one. For example, the renminbi is very much a corner, the ten horns is a dollar, and then a hundred, a hundred, a thousand, a million and so on. But not all are true, you can also use non-decimal count. For example, time, sixty seconds for a minute, sixty minutes for an hour, is a hexadecimal; twelve months for a year, is a binary system. Another example is usually said that a dozen pencils for the twelve, is also a binary; and two shoes for a pair, it is binary, and so on. In the electronic digital computer, is to use every binary binary.
