ATAND
Function
(1) Evaluates the arctangent function on the value specified for
to define an angle, and
stores the result to the word device specified for
.
(2) The angle (operation result) stored to
is stored in radians.
0 or values between 2
-1022
and 2
1024
can be specified.
For more information on the conversion between radians and degree, refer to the DEGD and
RADD instructions.
(3) When the operation results in
−
0 or an underflow, the result is processed as 0.
