问题描述
我打电话外部函数需要浮动[]
,但我的数组是浮动< M> []
。
我怎么会从阵列剥离的度量单位?
我需要的东西像下面的功能,但是这并不编译。
而且我想,以避免阵列中的任何迭代或者复制,因为浮动< M>
和浮动
值是相同的...
让demeasure(ARR:浮动< M> []):浮法[] =浮动[](ARR)
我认为,强制转换为 OBJ
,随后动态转换为浮动[]
会的工作,如:
(ARR:> OBJ):>浮动[]
因为没有运行时再presentation。

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)
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.
