*1: Applicable for the Universal model QCPU only.
Function
(1) Returns the TAN-1 angle of the TAN value designated by , and stores operation results at
word device designated by .
(2) 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.
: TAN value of which the TAN-1 (inverse tangent) value is obtained or head number of the devices where the
TAN value is stored (real number)
: Head number of the devices where the operation result will be stored (real number)
