Minor Description
When it comes to indexing floating-point data, doubles and floats are quite space-intensive even though full precision is rarely needed. So maybe we should consider exposing half floats?
Half floats have 5 bits for the exponent and 11 bits (including the implicit bit) for the mantissa so the minimum value is ~6x10−8, the maximum is 65504 and they can represent all integers between -2048 and 2048 accurately.
