I just noticed this one:postgres=# select 1000.000::float;
float8
1000(1 row)
postgres=# select 1000.0001::float;
float8---
1000.0001(1 row)
postgres=# select 1000.000100::float;
float8---
1000.0001(1 row)

What would be the easiest way to get back only the meaningful digits of
a numeric value in a pgsql function? eg?
1.002 -- 1.002
1.020 -- 1.02
1.200 -- 1.2
1.000 -- 1
Thanks

There are various rounding functions built in... have a look at

ROUND function might help you there:select round(1.2000::numeric, 1);Regards,Shoaib MirEnterpriseDB (www.enterprisedb.com)

You can use trim for this:
test=* select 1.020 +
Yep, I think this is it:
select trim(trailing '0.' from 1.020)
Many thanks.
