Why double and decimal columns changed?

[ThePlatinum]

Working with Laravel 11, I noticed a change in the column types for double and decimal. I am wondering why and I would love if someone can explain why the new way is better:

Here are screenshots and texts from the official doc to help explain the change.

From Laravel 11, only the decimal column had the precision and scale

The decimal method creates a DECIMAL equivalent column with the given precision (total digits) and scale (decimal digits): $table->decimal('amount', total: 8, places: 2);

The double method creates a DOUBLE equivalent column: $table->double('amount');

From Laravel 10, both the decimal and double column had the precision and scale

The decimal method creates a DECIMAL equivalent column with the given precision (total digits) and scale (decimal digits): $table->decimal('amount', $precision = 8, $scale = 2);

The double method creates a DOUBLE equivalent column with the given precision (total digits) and scale (decimal digits): $table->double('amount', 8, 2);

Thank you.

Decimal type has not been changed, just float and double types have been rewritten to be consistent across all databases.

You may check the explaination on the upgrade guide:

And also the releared PR: #48861
