(1) TAN (arctangent) operation is performed on the TAN value data specified with
(S) to find an angle.
(2) The operation result is in an angle (degree) unit.
(3) If (S) is an integer type, it is converted into a floating-point type before operation is
performed.
(1) An operation error will occur if:
• (S) is an indirectly specified device and its device No. is outside the range.
