D does have pow and many other useful math functions [1], it's just not defined for BitInts. Oh, and speaking of C, you also have access to all the usual C math [1] functions with just an import:

```d
import std.stdio : writeln;
void main()
{
     import std.math : pow;
     writeln(pow(10, 3)); // pow from D
     
     import core.stdc.math : pow;
     writeln(pow(10, 3)); // pow from C
     
     // can also make it more explicit to show where it is coming from:
     import cmath = core.stdc.math;
     writeln(cmath.pow(10, 3));
}
```

Have fun with D!
