@Qinclude 请直接使用 cout 输出答案，每行一个数字。

#13为什么是int存啊，显然double啊

by W_churchill @ 2020-05-08 19:35:26

第13问输出100000

@Qinclude #13要用到小数，用float

by 小个子 @ 2020-05-08 19:37:33

@tangrunxi double 更好吧

by W_churchill @ 2020-05-08 19:37:47

@tangrunxi float还是输出1000000

by Novice233 @ 2020-05-08 19:37:54

用long double啊

by tangrunxi @ 2020-05-08 19:38:16

@小个子 对 懒得用double

by tangrunxi @ 2020-05-08 19:38:31

@Qinclude 那就要double 这题这么卡精度？
