Operands:
S: Source device (0°≦S＜360°) D: Operation result
Explanations:
1. COS instruction performs cosine operation on S and stores the result in D.
2. The value in S can be set as radian or degree by flag M1018.
3. M1018 = OFF, radian mode. RAD = degree ×π/180.
4. M1018 = ON, degree mode. Degree range: 0°≦degree＜360°.
5. Flag: M1018 (Flag for Radian/Degree)
6. See the figure below for the relation between the radian and the operation result:

S: Radian
R: Result (COS value)
7. If operation result in D is 0, Zero flag M1020 = ON.
Program Example 1:
M1018 = OFF, radian mode.
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.
