Introduce the decimal scalar type

[speller]

Description

Many applications work with money, weights, dimensions. Many applications store data in DECIMAL database fields. It would be nice if this data type will be supported by the PHP core without workarounds like bcmath. It is unintuitive to use string typehints for decimal numbers instead of just "decimal". In PHP8, passing float values to bcmath may lead to issues (sic!). It is unintuitive to use functions for math operations instead of just + - / * etc. With the native decimal support, the bcmath extension can be retired.

With the native decimal support, the bcmath extension can be retired.

BC Math has more uses than new decimal type could handle, so no.

There is a pecl extension, please take a look http://php-decimal.io/ . To add this functionality to PHP the RFC will be necessary. Also please contact internals mailing list.

Thank you for this issue! As mentioned, this requires discussion on the mailing list, so GitHub issues aren't a good fit for making this happen.
