 ##1-Wire Library
 The Maxim DS-Family of thermometers use the 1-Wire microLAN protocol. There is an excellent library for 1-Wire, written by Paul Stoffregen and located at http://www.pjrc.com/teensy/td_libs_OneWire.html. 
 There is also an informative page at http://playground.arduino.cc/Learning/OneWire describing how to use the library. As there are parts of the code that are unnecessary for this DS implementation and 
 to make this library useable without having to download other libraries or components, the code from version 2.0 (extracted 2016-11-23), has been included.
 
 ## Public methods
-The DSFamily library has the following publicly accessible variables and functions:
+All returned temperature values are signed 2-byte integers (int16_t) of which only 12 bits are used, negative numbers are represented in the standard 2s complement form. The units returned are the
+raw DS-Family units which are 0.0625°C each.  Thus a device value of "325" would equate to 20.3125°C. To avoid floating point, I will multiply by 625 and then divide by 100, giving an integer "2031" which would be the
+temperature Celsius times 100; or hectodegrees. This gives 2 digits of precision but will still allow all temperatures to fit into a 16 bit number.
