The part I find strange is that the first one evaluates to true, since numeric can exactly represent 1.1 and float8 cannot. It also seems inconsistent with this: test=# set extra_float_digits = 3; SET test=# select '1.1'::float4; float4 ------------ 1.10000002 (1 row) test=# select '1.1'::float8; float8 --------------------- 1.10000000000000009 (1 row) -- Kevin Grittner EDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list ([email protected]) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
