Program Example
(1) The following program performs a TAN-1 operation on the sign (positive when X0 is OFF,
and negative when X0 is ON), the BCD 4-digit integer part from X20 to X2F and the BCD
4-digit decimal fraction part from X30 to X3F, and outputs the calculated angle in 4 BCD
digits from Y40 to Y4F.
