Thread: percision display

hey my question is i have a program that computers the power and the source code is like
this:

Code:

#include <stdio.h>

int main(void)
{
    int exp,c;
    double pow=1,bse;
    scanf("%lf %d",&bse,&exp);
    for(c=0;c<exp;c++)
         pow*=bse;
    printf("%f ",pow);
    return 0;
}

Input is : 95 12
Output is: 540360087662636990000000.000000

My question is that the output is not really accurate because when i type it on the
calculator the output is this :540360087668636962890685 could someone explain to me
why this happens?? and if how could i program correctly so that i could came out an
accurate output.. Thanks!

umm there's other alternative solution than having that library??

ohh thanks a lot salem for the hint....
