为什么我的输出是100.00
给定平面任意两点坐标(x1,y1)和(x2,y2),求这两点之间的距离(保留
2位小数)｡要求定义和调用函数dist(x1,y1,x2,y2)计算两点间的距离｡
提示：表示坐标及距离的变量是double型
输入10 10
200 100
输出210.24

0.1872×[(22.0-16.39)/100.00]×172.206/3 此分析式结果取几位有效数字?
规则我知道，你只需要说这个式子结果取几位有效数字

有效数字!
100.0是四位有效数字嘛
那100.00呢?
还有100.01跟100.1
可是1000只有一位有效数字啊
那100.01应该有五位有效数字吧？
