COSD, COSDP
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 32-bit floating decimal point type real numbers at D0 and D1.
[Ladder Mode]
[List Mode]
[Operations involved when X20 to X2F designate a value of 60]
: Angle data of which the COS (cosine) value is obtained or head number of the devices where the angle data is stored (real number)
: Head number of the devices where the operation result will be stored (real number)
