12.3456000000
(1 row){noformat}
MySQL:
{noformat}
select CAST(CAST(12.3456 AS DECIMAL(20,10)) AS CHAR(20));
12.3456000000

> Casting a decimal to a String doesn't do left zero padding

> Reporter: Marios Trivyzas
> Priority: Major

> *CAST(a AS STRING)* where *a* is a *DECIMAL(5.3)* with value *9.87* results in
> *9.870* so we only get right 0 padding to fill in the fractional digits.
>
> Postgres and Oracle also don't do left zero padding.
