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?

Aah, too quick on the trigger.

Also:

Is there a home brewed version of CONCAT() in the search_path?

Thanks.
