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