无法使用C计算给定数字的第5个根 [英] Trouble calculating 5th root of a given number using C
问题描述
嗨朋友
请帮我编写一个C程序来查找给定数字的第五（第五）根。
Ex：（1 ）输入：32
输出：32的第5根是2
例如：（1）输入：243
输出： 243的第5根是3

是否允许使用标准math.h？
如果是，那么
double result = pow（32,1 / 5）;
应该给你2.0

优点。
我通过DS9K运行了一些代码，现在到处都有鼻子
恶魔:-)
等待你的回复。

是否允许使用标准数学.h？
如果是这样，那么
双结果= pow（32,1 / 5）;
应该给你2.0
幸运的是，它给我1.0预期:-)也许你的意思是这个？：
double result = pow（32,1 / 5。）;
-nrk。

或者至少1.0。尝试1.0 / 5.0。
这种方法足以完成家庭作业，
但不是工业强度。

Hi Friends
Please help me to write a C program to find the 5th (fifth) root of a given number.
Ex:(1) Input : 32
Output : 5th root of 32 is 2
Ex:(1) Input : 243
Output : 5th root of 243 is 3

Is one allowed to use the standard math.h ?
If so, then
double result = pow(32, 1/5);
should give you 2.0

I ran some of the code there through the DS9K, and now there are nasal
demons all over the place :-)
Waiting for your reply.

Fortunately, it gives me 1.0 as expected :-) Perhaps you meant this?:
double result = pow(32, 1/5.);
-nrk.

should give you 2.0
Or 1.0 at the very least. Try 1.0/5.0.
This approach is good enough for a homework assignment,
but not industrial strength.
