Remove decimal & padding 0

Question

using Oracle 9i
I need to remove the decimal from a given number
123.45 should show as 12345 i tried this
create table tmpTBL
as
select 25.750 amt from dual
union all
select 12 from dual;
select replace(amt,'.',null) from tmpTBL
this works fine, but what if the col has amouts without decimals
123 should show as 12300
if decimal is there then remove it
else pad the number with '00'
how do i achieve this?
Thanks

Answer 1

Why not simply multiply by 100 ?Perhaps because that assumes no more than 2 decimal places?
