why big numbers change in floating-point variables?
hi i don't know why but some of the values change on their own when i run this code. why?
Code:
#include <stdio.h>
#include <math.h>
int main(void)
{
double a = 111 * pow(10,20);
double b = 128 * pow(10,20);
double c = 255 * pow(10,20);
double d = 256 * pow(10,20);
double e = 10 * pow(10,20);
printf("%f\n%f\n%f\n%f\n%f\n", a,b,c,d,e);
return 0;
}
my output:
Code:
11100000000000001048576.000000
12800000000000000000000.000000
25500000000000001048576.000000
25600000000000000000000.000000
1000000000000000000000.000000
if you look at the output the first and third value changed on their own.
