    Hi,Ed

    You'll get -127 to +127 as a result ... so, look at the highest digit to see where you are on your sine ( ascending = 1, descending = 0 ).

    But do not forget to convert degrees as here:

    Result = COS ( X * 256 / 360 ) ... for X in degrees.
    Side = Result.7

    Looking also to SIN highest digit will show you the quarter where you are ...

    For accuracy ... 7 bits !!!
