You can use std.conv.toChars:

```d
void main() @nogc
{
    int n = 515;

    import std.conv;
    char[10] s = 0;
    auto r = n.toChars();
    assert(r.length < s.length);
    size_t i;
    foreach (c; r)
        s[i++] = c;

    import core.stdc.stdio;
    puts(s.ptr);
}
```

Or, using std.experimental.allocator:

```d
void main() @nogc
{
    int n = 515;

    import std.conv;
    import std.experimental.allocator;
    import std.experimental.allocator.mallocator;
    alias a = Mallocator.instance;
    auto s = a.makeArray(n.toChars);
    assert(s == "515");
    a.dispose(s);
}
```
