Something like one of these two:

B4X:

Log(NumberFormat(201/10,1,1))    'displays: 20.1
Log($"${NumberFormat(201/10,1,1)}"$)   'displays: 20.1

Yes, but then I already need a double.
The "201" is in a string, so I need to convert the string to a number OR I need to put a decimal in between.

You could Looop through the string and check every char in the string if it is a number. if so you could add it to another string linke this:

dim number as string

For each c as Char in String
If Isnumber(c) then
number = number & c
end if
Next

Yes, but this gives an error:

B4X:

Dim String1 as string = "201"
Dim String2 as string

String2 = NumberFormat(String1/10,1,1))

The above code will work after you remove the extra closing parenthesis.

in B4J this works fine

B4X:

Dim str1,str2 As String
str1="201"
str2=str1/10
Log(str2)

and output 20.1
