ACOS(P)

*1: Applicable for the Universal model QCPU only.

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.
