Only required in java, also without using strings or any specific objects, (just use maths)

problem is

```
double a = 13.564;
//now i want
int b = 13;
int c = 564;
```

### >Solution :

Using String it would be easier as we don’t need to know how many decimal there is

```
double a = 13.564;
String[] parts = Double.toString(a).split("\\.");
int b = Integer.parseInt(parts[0]);
int c = Integer.parseInt(parts[1]);
System.out.println(b + "/" + c);
```

With math only, you need to be careful so, a way is so multiply the number so there is no decimal part, the retrieve what was the decimal part

```
double a = 13.564;
int b = (int) a;
double power = Math.pow(10, BigDecimal.valueOf(a).scale());
int c = (int) (a * power - b * power);
System.out.println(b + "/" + c);
```
