Notes on operand usage:
Refer to the function specifications table for each device in series for
the scope of device usage.
 S: the designated source value (diameter). D: the COS value result.
 Finds the COS of the source value designated by S and stores it in D.
The following figure displays the relationship between the arc and COS results:
 When X0 = ON, finds the COS value of the designated binary floating point number
(D1, D0) in radians and stores the result in (D11, D10), as a binary floating point
number.
