• The following program performs a TAN operation on the angle data set by the 4 BCD digits from X20 to X2F, and stores the
results as 64-bit floating decimal point type real numbers at D0 to D3.
[Ladder Mode]
[List Mode]
[Operations involved when X20 to X2F designate a value of 135]
Inputs an angle used for TAN
operation ( ).
Converts the input angle into a
64-bit floating-point real number ( ).
Converts the converted angle into a
radian value ( ).
Executes TAN operation using the
