Subject: Inconsistent results for division and multiplication operations

Hi PostgreSQL community,


I have observed inconsistent results when performing division and multiplication operations in PostgreSQL.


postgres=# select 1.003/1.002*5.01;
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;?column?
--------------------------
&nbsp;5.0149999999999999999806&nbsp;&nbsp;
(1 row)


postgres=# select 1.003*5.01/1.002;
&nbsp; &nbsp; &nbsp; ?column?
--------------------
&nbsp;5.0150000000000000
(1 row)


However, the expected result should be consistent for both queries. The actual results differ
