> 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.
