从 Power Query 中的列表中提取小数

Question

我正在尝试从字符串中提取十进制数。 我有一个可行的解决方案，但我认为可以用更好的方式完成，

---

以下 M 代码完成工作，

let
    Source = Excel.CurrentWorkbook(){[Name="Table21"]}[Content],
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each List.FindText(Text.Split([Column1]," "),".")),
    #"Expanded Custom" = Table.ExpandListColumn(#"Added Custom", "Custom"),
    #"Changed Type1" = Table.TransformColumnTypes(#"Expanded Custom",{{"Custom", type number}}),
    #"Removed Errors" = Table.RemoveRowsWithErrors(#"Changed Type1", {"Custom"})
in
    #"Removed Errors"

但我想从列表中提取小数

---

我应该在之前添加什么

List.FindText(Text.Split([Column1]," "),".")

只提取十进制数。
