Processing details
• These instructions calculate the tangent of the angle specified by (s), and store the sign of the operation result in the device
specified by (d) and the operation result in the devices specified by (d)+1 and (d)+2.
(d)
TAN (s) =
(d): Sign
(d)+1: Integral part
(d)+2: Decimal part
• For the value to be specified in (s), set a value from 0 to 360(in the DEG. unit) as a BCD value.
• For the sign of the operation result to be stored in the device specified by (d), 0 is stored when the operation result is
positive and 1 is stored when the operation result is negative.
• The operation result to be stored in the devices specified by (d)+1 and (d)+2 is a BCD value in the range from -57.2901 to
57.2903.
• The operation result is a value whose 5th decimal place is rounded off.
