How to trim duplicated values in a string KQL?

I have the following data sample:

let data = datatable(Name:string, Value:string)
            [
                "Device_1", "60.12.12 %",
                "Device_2", "40.12.12 %",
                "Device_3", "50.12.12 %",
                "Device_4", "48.33.33 %"
            ];

As you can see in the Value column, the values after the decimal points are duplicated.

How can we trim the second decimal point and the values after it ?

Expected result:

>Solution :

let data = datatable(Name:string, Value:string)
            [
                "Device_1", "60.12.12 %",
                "Device_2", "40.12.12 %",
                "Device_3", "50.12.12 %",
                "Device_4", "48.33.33 %"
            ];
