Considerations:
data type int, bigint, smallint, tinyint, or decimal or numeric with
a scale of 0
SQL Server will allow you but its not recommended mainly because
floats are inaccurate as @Andy said.
why do you need a float as a PK anyway? Do you need a value like 3,1234235234534 to uniquely identify your row?
