Subject: [PHP-DEV] Add a static initialization method to `BcMath\Number`
Message-ID: <AA13E6BB-2B3F-4E5D-9E9A-A60D857EDCD5@sakiot.com>

Hi internals!

In this issue, a suggestion was made that it would be convenient if `BcMath\=
Number` could be initialized in a callable-style form (i.e. initialized via a=
 static method):
https://github.com/php/php-src/issues/22128

Indeed, as pointed out in the issue, similar static methods exist in classes=
 such as `DateTime`.

I am in favor of introducing such a static method. It would probably look so=
mething like this:

```
// $scale is optional
$num =3D BcMath\Number::createFrom($val, $scale);
```

It would effectively serve as an alias for the constructor.

Incidentally, since this does not introduce any BC break, I do not believe a=
n RFC is necessary.

I would like to hear everyone=E2=80=99s thoughts on this.

Regards,

Saki=
