Function
(1) Returns the COS
-1
angle of the COS value designated by , and stores operation result at
word device designated by .
(2) The COS value designated by can be in the range of from 1.0 to 1.0.
(3) The angle (operation result) stored at is stored in radian units.
For more information on the conversion between radian and angle data, see description of
RAD and DEG instructions.
