TAN, TANP
[Operations involved when X20 to X2F designate a value of 60]
: Angle data of which the TAN (tangent) value is obtained or head number of the devices where the angle data is stored (real number)
: Head number of the devices where the operation result will be stored (real number)
*1: Applicable for the Universal model QCPU, LCPU.
Function
(1) Returns the tangent (TAN) value of the angle data designated by , and stores operation result in device designated by
.
(2) Angles designated at are set in radian units (degrees / 180).
For conversion between degrees and radian values, see the RAD and DEG instructions.
(3) When angles designated by 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.
