Question

I am calling external function requiring float[], but my array is float<m>[].
How could I strip the unit of measure from array?

I need something like the function below, but this does not compile.
And I would like to avoid any iterating or duplicating of the array, as float<m> and float values are identical…

let demeasure (arr:float<m>[]): float[] = float[] (arr)

Answer 1

I believe that a cast to obj, followed by a dynamic cast to float[] would work, e.g.

(arr :> obj) :?> float[]

because there is no runtime representation.
