having a Double result in c++?

Question

when having a double result how can i have .50 print out inmy result. for example 1.50 or 2.5o or 3.50 but i only want the .50 printed out, not the entire number just the decimal

Answer 1

float d = 1.50
float e = d - ceil(d);
printf("%f",e)

Answer 2

Example:
Floatig Number as for instance double d1 = 3.5
1.) Cast into integer from float or double:
int n = d1; //results in n = 3
2.) Subtract d1 from n results in 3.5 - 3 = 0.5:
double d2 = d1 - n; //resulting in d2 = 0.5
If you wish only to display ".5" instead of "0.5", then you can convert it into a string and remove the first index of the string; namely, the zero "0".

Answer 3

#include

cout.precision(2) ;
cout << 45.678 << endl;


/** GOOD LUCK **/

Answer 4

double num=3.05;
printf("%.2f",num);
