[Improvement]: Numeric Editable should have placeholder and/or default value

[marvin-bilharz]

Improvement description

The documentation for numeric editable states "The numeric editable is very similar to the input editable" therefor it should have the same placeholder option as the input. This would be helpful to display the default value, if nothing is typed in for the input. Since we do not have a default value for input/numeric, which would also be an improvement.
