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;

         ?column?

--------------------------

 5.0149999999999999999806  

(1 row)

postgres=# select 1.003*5.01/1.002;

      ?column?

--------------------

 5.0150000000000000

(1 row)

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