Setting data
Angle data for which the TAN (tangent) value is obtained or the first number of the
S
device where angle data is stored.
D The first number of the device to store the operation result.
 Functions
TAND
 Returns the TAN (tangent) value of the angle designated by (S) and stores the operation result in the device number desig-
nated by (D).

 Angles designated by (S) are set in radian units (degrees x π / 180). For conversion between degrees and radian values,
refer to the RADD and DEGD instructions.
 When angles designated by (S) are π/2 radians, or (3/2)π radians, note that because an arithmetic error occurs in the
radian value, an error will not occur.
 When the operation results in "-0" or an underflow occurs, the operation result is processed as "0".
 When setting input values from programming tools, rounding errors may occur.
For precautions when setting input values from programming tools, refer to "6.3.4 Single/Double-Precision Real Number
Data".
