Floating point math itself is not precise, but rather an approximation, usually of 8 or 14 digits. You can't approximate money. This isn't a PostgreSQL issue but rather a general programming issue.
Thanks, Bruce. I assume the arbitrary precision arithmetic Jan mentioned which is used for the NUMERIC type takes care of this.
That was the whole intention. Although Bruce is wrong, since most of the time money is approximated. It is only in "bookkeeping" where this is not allowed.
Yes I agree with you Jan , most of the time we round the amount and this is done by truncating greater than 3 decimal digits and rounding the 3 digit to 2 in other words :
select trunc(1000.236897,3);
then
selecr round(1000.236,2);
This takes care of the rounding factor in money as per Indian standards ok, how will you verify it simple just use log and you will get the correct output.
