inconsistent length for range buffers

[daslu]

Here is an interesting phenomenon:

$ clj -Sdeps '{:deps {cnuernber/dtype-next {:mvn/version "10.124"}}}'

user=> (require '[tech.v3.datatype :as dtype])
nil

user=> (->> (range 2 3 0.01)
     count)
101

user=> (->> (range 2 3 0.01)
     (tech.v3.datatype/emap identity :float32)
     count)
100

Probably it is related to the fact that the different between the range start an end is close to a multiple of the step size.
Not all step sizes are problematic:

ser=> (->> (range 2 3 0.0099)
     count)
102

user=> (->> (range 2 3 0.0099)
     (tech.v3.datatype/emap identity :float32)
     count)
102

The issue seems important since it affects column addition in tech.ml.dataset:

$ clj -Sdeps '{:deps {techascent/tech.ml.dataset {:mvn/version "7.034"}}}'
Clojure 1.12.0

user=> (require '[tech.v3.dataset :as ds])
nil

user=> (-> {:x (range 2 3 0.01)}
    ds/->dataset
    (ds/column-map :y identity [:x]))

Error printing return value (IndexOutOfBoundsException) at ham_fisted.Ranges$DoubleRange/lgetDouble (Ranges.java:186).
Index out of range: 100 size: 100
