Function
(1) The angle is calculated from the COS (cosine) value specified by is and its result is
stored into the device specified 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
RADD and DEGD instructions.
(4) When the operation results in -0 or an underflow, the result is processed as 0.
: COS value of which the COS
-1
(inverse cosine) value is obtained or head number of the devices where the
COS value is stored (real number)
: Head number of the devices where the operation result will be stored (real number)
