Hello,

Thank you for this insight...  but I tried to enter "20.00" into a:
foo numeric type
foo float4 type
or even a:
foo numeric(12,2) type

with the same result: a select foo::numeric from table; always gives me "20"
just like select foo from table;

In the case of numeric(12,2), I always get the trailing double digits... so
"20" entered gives "20.00" with the select foo (with or without the
::numeric).

??? Did miss something from your explanation or is it my 7.1.x version taht
is the problem?

Thanks,
