For example, if you take two readings of 90 and 270, what should the answer be? 0? 180? never (...) (19 years ago, 5-Aug-05, to lugnet.org.ca.rtltoronto)

For example, if you get readings of 10 deg and 20 deg, but in the time between the direction was never 15 (...) (19 years ago, 5-Aug-05, to lugnet.org.ca.rtltoronto)
