MySQL, Math functions and Decimal type.

[Sergio Minervini]

Do all of the MySQL mathematics functions, as per

https://dev.mysql.com/doc/refman/8.0/en/mathematical-functions.html

work directly and successfully on numbers of type DECIMAL?

-So if I have successfully inserted into a table defined by the field

'numbers DECIMAL(6,3)', the value

123.456

and want to take

select cos(numbers) from data_table;

will this run directly, WITHOUT me having to invoke cast
to try and change types?
