TAND( P)
7.12.6 TAN operation on floating-point data (Double precision)
(TAND(P))
TAND(P)
Function
(1) The TAN (tangent) value of the angle specified by is calculated and its result is stored into
the device specified by .
(2) Angles designated at are set in radian units (degrees / 180).
For conversion between degrees and radian values, see the RADD and DEGD 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.
(4) When the operation results in -0 or an underflow, the result is processed as 0.
: 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)
