Operands:
S: Source value D: TAN result
Explanations:
1. 0° ≤ S < 360°. See the specifications of each model for their range of use.
2. Flags: M1018 (angle or radian); M1020 (zero flag)
3. S can be an angle or radian, decided by M1018.
4. When M1018 = Off, the program will be in radian mode and the RAD value = angle ×
π/180
5. When M1018 = On, the program will be in angle mode and the range of angle should be “0° ≤ angle < 360°”
6. If the result = On, M1020 = On.
7. The TAN value obtained by S is calculated and stored in the register designated by D. The figure below offers the
relation between radian and the result.
S: Radian
R: Result (TAN value)

Program Example 1:
When M1018 = Off, the program is in radian mode. When X0 = On, use the RAD value of binary floating point (D1, D0)
and obtain its TAN value. The binary floating point result will be stored in (D11, D10).
