Error when adding float numbers, what's wrong?

Question

SQLite

there is a database where real numbers are stored, I pull them out from there and add them to the total number, but for some reason 325.40000000000003 comes out of these numbers 23.0 / 15.0 / 70.0 / 61.0 / 61.2 / 6.0 / 33.0 / 15.0 / 35.3 - these the numbers that I pull out of the database, which are stored there as real
