7.12.4 COS operation on floating-point data (Double precision) (COSD(P))
Program Example
(1) The following program performs a COS operation on the angle data designated by the 4
BCD digits from X20 to X2F, and stores 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 60]
Inputs an angle used for
COS operation ( ).
Converts the input angle into a
64-bit floating-point real number ( ).
Converts the converted angle
into a radian value ( ).
Executes COS operati
on using the
converted radian value ( ).
