The Javadoc of the @Column annotation clearly says that precision is only supported for decimal/numeric types and that the unit is decimal digits. Providing a precision for float/double types is “unspecified“. So far, Hibernate 5 just ignored the value you have been providing. Hibernate 6 now interprets this as decimal digits, just like for decimal/numeric types. It translates the value you provide to the binary digit precision by calculating decimal_precision*ln(10)/ln(2).
