Ah I see! It sounds exactly like `number_format`. Sure, this might make sense.
To me, this seems worth supporting.
BTW,
```
$bcNum = new BcNum('1234567890123456789.23456789’);
```
When I saw this, I thought that the behavior when $scale is omitted is that in
addition to the option of "using the global setting value", there is also the
option of "counting the length of `$num` and storing all `$num`”. In other
words, it does not use any global settings.
Which of these do you think is better?
Regards.
