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 ...
