I don't think it's a case of "sometimes but not always". Instead there's a contagion precedence order such that any type earlier in the order combined with a type later in the order yields the type later in the order. Here's the order: Long < BigInt < Ratio < BigDec < Double Before applying the contagion order, narrower integer types are promoted to Long, and float is promoted to Double.
