1900) An analog input module uses an A/D converter with 8-bit resolution.  
   The module range is -10 volts to +10 volts. Calculate the module output 
   (digital count) when the input voltage is 3.7 volts. 1) floating point 
   calculation, 2) discrete rounded result (actual digital count), 
   3) answer-2 minus answer-1 and 4) voltage resolution or smallest detectable 
   change (volts).  Assume the minimum digital value is zero. ans:4
