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 (binary floating point number). D: the ACOS value result.
 ACOS value = cos
-1
The figure below shows the relationship between input data and result:
 When X0 = ON, finds the ACOS value of the designated binary floating point
number (D1, D0) and stores the result in (D11, D10), as a binary floating point
number.
