Comment (by cornofear):

 In the original ticket Tupsi said:

 'so I even tried numbers like 50 in the hopes it means "5.1", as I do not
 understand how the 14 current options listed above are represented by
 integer number between 0 und 186 (which says so in the help). I tried both
 left the labels 5.0, 5.1, 4.0, even 1.0 as well as differnt integer
 numbers in between 0 and 186.'

 To avoid this problem, I'd suggest changing the help text to list the
 constants 'auto, 1.0, 2.0 etc,'

 Even better would be to use the following code by AMD to parse this value:
