replacing value in a table such as <5 to make it 5, then convert to number and half it

[Anonymous]

so i have a set of data with loads of <x values , i would like to get rid of the "<" part of the text and leave the number , and with the numbers thatt previously contained a "<" i would like to divide that number by 2

@Anonymous in query editor, use replace feature to replace < with "" and then convert your column to  number field. Add another custom field and divide your original number field with 2.

the problem is that the number column contains values such as

5

1

<4

4

6

6

<6

3

i only want to delete the "<"  and half the numbers that prevously contained "<" and leave the values that didnt contain the "<" alone

@Anonymous got it, here is query, just create blank query and in advanced editor paste this code, change it as per your need

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlWK1YlWMgSTYCKm1MDAONkEIYDENMPKhOhAEjBWio0FAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Col = _t]),
    #"Filtered Rows" = Table.SelectRows(Source, each ([Col] <> "")),
    #"Duplicated Column" = Table.DuplicateColumn(#"Filtered Rows", "Col", "Col - Copy"),
    #"Replaced Value" = Table.ReplaceValue(#"Duplicated Column","<","",Replacer.ReplaceText,{"Col - Copy"}),
    #"Changed Type" = Table.TransformColumnTypes(#"Replaced Value",{{"Col - Copy", type number}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each if Text.Contains([Col],"<") then [#"Col - Copy"] / 2 else [#"Col - Copy"]),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"Col", "Col - Copy"})
in
    #"Removed Columns"
