Weight in Stones and Pounds

Is it possible to fix the current 'Stones and Pounds' measurement?  It seems to round up using a decimal system. For example:

I have recently gone from 16 Stone 00 Pounds to 15 Stone and 11 Pounds.  If I enter 15.11 into the Shapelink system it automatically drops of the last '1' and shows my weight as 15.1!  Don't get me wrong that would be fantastic!! But the reality is I am long way of that yet 

I would really like to see my weight loss depicted correctly.

Kind regards
