        0
(1 row)

As you said ...

So make everything decimal:
billing=# select 1.0/100.0;

        ?column?

 0.01000000000000000000

Or:
billing=# select 1::decimal/100::decimal;

        ?column?

 0.01000000000000000000

I think that when you use integers you lose precision right out the gate. Others can provide better insight I hope ...

Do you need help?
