Given the following table, backed by MySQL 5.7/InnoDB:
CREATE TABLE mytable(mydouble DOUBLE) SELECT 0.005 `mydouble`;
how can I find what exactly InnoDB is storing on the disk for the value
I know that this varies depending on the architecture, so I'm looking for a methodology rather than a certain value. I'm a programmer/dba, so I'm handy with any tool, if required.
