Re: Bug #881: floor function returning double precision with integer arguments in 7.3, returns numeric in 7.2 with the same statement - Mailing list pgsql-bugs

PostgreSQL7.3 states that PostgreSQL 7.3's floor function should return type numeric. In 7.3 it seems to be returning
thedouble precision datatype. Oracle 8.0.5 correctly executes the test statments along with PostgreSQL 7.2. (we have to

This table seems not to have been updated when we added float versions
of ceil(), floor(), and sign().  You won't get any support for ripping
them out again, though.  I suggest adding casts to the queries, or
possibly defining a version of mod() that takes float8.
