On the other hand, if allow the calculation method to specify a scale, we can
write it like this:
```
$num = new Number('1.23');
$num2 = new Number('4.56');
$result = $num->add($num2, 4);
$result->value; // '5.7900'
$result->scale; // 4
```
It's just one less line, but that's the only reason to support the `$scale`
argument.
If you write it as:
$result = $num->withScale(4)->add($num2);
it's not an extra line anymore. I also think that withScale() use will
be rare, as we have the scale in constructor.
I think the intention is more clear here, and I think it applies to all
cases you mentioned, including div or pow. If you know you need to
change the scale just add ->withScale(X) before.
