I am using Postgresql 10 and seeing a strange behavior in CONCAT function when I am concatenating double precision and int with a separator.

    select concat('41.1'::double precision,':', 20);
    Result:
    41.1000000000000014:20


Value 41.1 which double precision converts to 41.1000000014.

Is that expected?

No.

What OS and version of same?

How was Postgres installed?


Thanks.
