Wrong calculation when working with decimals

Hi,

 

I'm calculating a column that is just the product of two other columns, it works fin for most of the rows (the ones that have 9 decimal places) but it does not work when the cell from one of the columns has fewer decimal places. Any idea of why this might be?

The calculated column "Contribución" is the product of "Retornos.LM" and "Porcentaje Rebalanceado"

    let
        Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("LcrBDcAwCAPAXXinkWtIwLNE7L9GVKnvu3PswcSyYbPkSlGITG5ajx+DUSn/zosNIqFFppd1Xw==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t]),
        #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type number}, {"Column2", type number}}),
        #"Inserted Multiplication" = Table.AddColumn(#"Changed Type", "Multiplication", each [Column2] * [Column1], type number),
        #"Changed Type1" = Table.TransformColumnTypes(#"Inserted Multiplication",{{"Multiplication", Percentage.Type}})
    in
        #"Changed Type1"

      Greg_Deckler you're right, it was formatted as text, thanks!
