May be I miss something, but seems there is a problem with float4
in 7.2.3 and 7.3RC1 (6.53 works fine):
test=# create table t ( a float4);
CREATE TABLE
test=# insert into t values (0.1);
INSERT 32789 1
test=# select * from t where a=0.1;a
---
(0 rows)
test=# select * from t where a=0.1::float4; a
-----0.1
(1 row)
No problem with float8
test=# create table t8 ( a float8);
CREATE TABLE
test=# insert into t8 values (0.1);
INSERT 32792 1
test=# select * from t8 where a=0.1; a
-----0.1
(1 row)
Regards, Oleg
