Status: OUT
Scalar streaming accumulators achieve exact results for all inputs within LeetCode's constraint bounds because Python's arbitrary-precision integers prevent overflow and the repo systematically chooses integer arithmetic over floating-point — but this precision guarantee breaks for any solution that introduces floating-point division into the accumulation chain.
Integer accumulators are precision-safe by Python's arbitrary-precision guarantee, gated on no float division in the accumulation path
