十进制数系

该系统采用十进制数,它包括10个基地,由数字0至9. 不要混淆,这是我们共同的系统使用人数在日常生活计算的东西. 加权权值为每状况如下:

(Base 10)Number

104

103

102

101

100

10-1

10-2

10-3

Value

10000

1000

100

10

1

.1

.01

.001

如果我有这样一个十进制数218,我想它代表人数218名以上的方式将代表选举方式如下:

2 * 102 + 1 * 101 + 8 * 100

= 2 * 100 + 1 * 10 + 8 * 1

= 200 + 10 + 8

= 218

现在让我们以一个例子任何分数小数号码.让我们有若干821.128.每个数字呈现小数点左侧的值是在零和十个有九个和电力为代表的立场多少(由0).

数字呈现的是一个正确的小数点值零度至九倍增加负十次方.请看:

8 * 102 + 2 * 101 + 1 * 100 + 1 * 10-1 + 2 * 10-2 + 8 * 10-3

= 8 * 100 + 2 * 10 + 1 * 1 + 1 * 0.1 + 2 * 0.01 + 8 * 0.001

= 800 + 20 + 1 + 0.1 + 0.02 + 0.008

= 821.128
