I read somewhere about other data structures similar to hashtables, dictionaries but instead of using ints, they were using floats/doubles, etc.
Anyone knows what they are?
If you mean using floats/doubles as keys in your hash, that’s easy. For example, in .NET, it’s just using
Dictionary<double,MyValueType>.If you’re talking about having the hash be based off a double instead of an int….
Technically, you can have any element as your internal hash. Normally, this is done using an int or long, since these are fast, and the hashing algorithm is easy to compute.
However, the hash is really just a BitArray at heart, so anything would work. There really isn’t much advantage to making this something other than an int or long, other than potentially allowing a larger set of hash values (ie: if you go to an 8 byte or larger type for your hash).
