Answer 1

5/100 is integer arithmetic. In order to have double precision one or more of the values need to be doubles.

double result = 5.0/100.0;  
double result = 5.0/100;  
double result = 5/100.0;  
double result = (double)5/100;  
double result = 5/(double)100;

or

double numerator = 5;  
double denominator = 100;  
double result = numerator / denominator;
