Program Example
(1) The following program calculates the cosine of the data designated by the 3 BCD digits from
X20 to X2B and outputs the integer part of the result to 1 BCD digit from Y50 to Y53, and the
decimal fraction part of the result to the 4 BCD digits from Y40 to Y4F.
Y60 is turned ON if the results of the operation are negative.
