I would still treat this as a bug, my vision the problem is DF cannot identify correctly decimal as a input and does implicit conversion to the f64 which is not expected. Both Postgres and Spark returns correct result for ``` select 6.4053151420411946063694043751862251568 + 1; 7.4053151420411946063694043751862251568 ``` whereas DF likely does unneccessary cast and thus loss of precision ``` ❯ select 6.4053151420411946063694043751862251568 + 1; +---------------------------------------+ | Float64(6.405315142041195) + Int64(1) | +---------------------------------------+ | 7.405315142041195 | +---------------------------------------+ 1 row in set.
