convert a float value to a nul-terminated array of characters with one digit to the right of the decimal point?
At this time I have no idea what a "nul-terminated array of characters" is exactly... 
My original request was just to get my value from the Thermister() function to show one digit after the decimal point. This was accomplished with a proper print statement.
And in doing that the incorrect code was mentioned regarding the averaging of the sensor reading. So the thread has kinda split....
