Operands:
Please refer to the specifications of each model for the
range of operands.
 S: Source device (0°≦S＜360°) D: Operation result
Explanation
 The value in S can be set as radian or degree by flag M1018.
 M1018 = OFF, radian mode. RAD = degree ×π/180.
 M1018 = ON, degree mode. Degree range: 0°≦degree＜360°.
 If result to 0, M1020 = On.
 COS instruction performs cos operation on S and stores the result in D
See the figure below for the relation between the radian and the operation result:
Example
When X0 = ON, DCOS instruction conducts cosine operation on binary floating

value in (D1, D0) and stores the COS value in (D11, D10) in binary floating format.
