Why the double type variable in C can't store the digit '7'?
I tested a double variable in C to store the value '12345678901234567'. But it can't store the last digit '7' and shows it as '8'. However, if I change the last digit to '6' or '8', then it can show the same value. What is that?
Here is the program:
#include <stdio.h>
int main()
{
double a;
a = 12345678901234567;
printf("%lf", a);
return 0;
}
Output: 12345678901234568.000000
