Subject: [PHP-DEV] BCMath: Supporting scientific notation

Hi all!

In the following issue, there was a proposal to add support for =
scientific notation in BCMath.
https://github.com/php/php-src/issues/17876

I agree with this and have already created a prototype.
https://github.com/php/php-src/pull/18068

The prototype allows to pass scientific notation values =E2=80=8B=E2=80=8B=
to both functions and classes in the same way as normal numeric string.

The Number class could add a method to convert strings to scientific =
notation, or it could simply not accept scientific notation in the =
constructor and create a dedicated static method for it.
We can also choose not to accept scientific notation in BCMath =
functions.

Could you please give your opinion on this?

Regards,

Saki
