WebApr 29, 2024 · @DocBrown The "not possible" part is correct. If epsilon based equality should imply that the hash codes are equal, then you automatically have all hash codes equal, so the hash function is not useful anymore. The buckets approach can be fruitful, but you will have numbers with different hash codes that are arbitrarily close to each other.

WebHigh-quality hash functions can be expensive. If the same values are being hashed repeatedly, one trick is to precompute their hash codes and store them with the value. Hash tables can also store the full hash codes of values, which makes scanning down one bucket fast. In fact, if the hash code is long and the hash function is high-quality (e.g ...
