pow() function

[Sytan]

Hello everyone,

Please allow me to ask about pow() function in math.h for Hi-Tech C compiler. I had tried the following:-

unsigned long temp;

temp = pow(10,1); // i get 10 for my answer *CORRECT
temp = pow(10,2); //i get 100 *CORRECT
temp = pow(10,3); //i get 1000 *CORRECT also

Problems arise when i tried

temp = pow(10,4); //i get 10001 for my answer which is not true for decimal
temp = pow(10,5); //i get 100016 for my answer..
higher power i go the error getting larger.

FYI,i need it in my FOR loop,any other method to get rid of this problem?
Thank you in advance

sorry
I think i found a way to solve it.
using loop to multiply variable itself will get the exact value i need
eg:-
temp *= X; //where X is your base

Haha...it's good that you found an alternative to get the desired result. About the problem using pow() function, I've no idea why the error occurs
