Hello,
I am trying to use pow with an integer argument, but I cannot have a bigint
result, for example, ```pow(10,72)```.
Do I have to write my pow function or is there a native solution?
thanks,
Fausto
In contrast to certain scripting languages, there's no implicit promotion, you
have to opt in for BigInt [1] usage in D:
```d
import std;
void main()
{
// all print the same
writeln(BigInt(10) ^^ 72);
writeln(10.BigInt ^^ 72);
writeln("10".BigInt ^^ 72);
}
```
