You can either use function `out` parameters with return value or 
`tuples`:
```D
import std.typecons;

// with tuples
auto getVal(int a, int b) {
     // ...
     return tuple(integer, frac);
}

// out params
int getVal2(int a, int b, out int frac) {
     // ...

     frac = _fraq;
     return integer;
}

// USAGE
{
     // with tuples
     auto v = getVal(5, 2);
     assert(v[0] == 2);
     assert(v[1] == 1);

     // with out params
     int frac;
     int integer = getVal2(5, 2, frac);
     assert(integer == 2);
     assert(frac == 1);
}

```
