Converting KB to MB, GB, TB dynamically

Question

public String size(int size){
    String hrSize = \"\";
    int k = size;
    double m = size/1024;
    double g = size/1048576;
    double t = size/1073741824;

            


        

Answer 1

The problem is that you're using integer division. Change your code to:

double m = size/1024.0;
double g = size/1048576.0;
double t = size/1073741824.0;

In your original code, double m = size/1024 would divide the integer size by 1024, truncate the result to an integer, and only then convert it to double. This is why the fractional part was getting lost.
