We already have some of those.
-many. We'd directly violate our own error rules. I'm actually personally in favor of not throwing error when float overflows - it's imo not actually useful and costs performance - but sometimes throwing an error depending on the specific register allocator behaviour of a specific version of a compiler is bad. It's really weird to return [+-]Infinity depending on just *how much* you overflowed. Greetings, Andres Freund
