what is the human readable format? Different countries have different readable format. would you please bring in example?

public void convert (long num ,int steps){
		if (num > 10) {
			long digit = num % 10 ;
			convert (num / 10 , steps + 1) ;			
			System.out.print(digit);
			if (steps != 0 && steps % 3 == 0) {
				System.out.print(',');
			}
		} else{
			System.out.print(num) ;
			if (steps % 3 == 0) {
				System.out.print(',');
			}
		}

}

#include <stdio.h>

int main()
{
    unsigned long long num = 47496747;
    char * str[] = {"byte(s)", "KB", "MB", "GB", "TB"};
    int depth = 0; 

    if(num < 1024)
        printf("%llu ", num);
    else
    {
        while((num / 1024) != 0)
        {
            num /= 1024;
            depth++;
        }
        printf("%.2f ", (float)num);
    }
    
    printf("%s\n", str[depth]);
    
    return 0;
}
