ATAND, ATANDP
: 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)
Function
(1) The angle is calculated from the TAN (tangent) value specified by is and its result is stored into the device specified 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 RADD and DEGD
instructions.
(3) When the operation results in -0 or an underflow, the result is processed as 0.
Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into
SD0.
