7.12 Special Function Instructions
TAN operation on floating-point data (single precision)
TAN(P)
*1 Applicable for the Universal model QCPU, LCPU.
Processing details
• Returns the tangent (TAN) value of the angle data designated by (S), and stores operation result in device designated by
(D).
• Angles designated at (S) are set in radian units (degrees   / 180). For conversion between degrees and radian values,
see the RAD and DEG instructions.
• When angles designated by (S) are /2 radians, or (3/2) radians, an operation error will be generated in the calculation of
the radian value, so care must be taken to avoid such errors.
• When an input value is set using a programming tool, a rounding error may occur. For precautions, refer to Page 89
Precautions.
Operation error
• In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into SD0.
*2 There are CPU modules that will not result in an operation error if -0 is specified. For details, refer to Page 87 Using single/double-
precision real number data.
• Basic model QCPU: The serial number (first five digits) is "04122" or later.
(S): Angle data of which the TAN (tangent) value is obtained or head number of the devices where the angle data is stored (real number)
(D): Head number of the devices where the operation result will be stored (real number)
