Operands:
S: Source value (binary floating point) D: ATAN value
Explanations:
1. See the specifications of each model for their range of use.
2. Flag: M1020 (zero flag)
3. ATAN value=tan
–1
. The figure below offers the relation between the entered tan value and the result.
S: Entered data (tangent value)
R: ATAN value (radian)

4. If the result =0, M1020 = On.
Program Example:
When X0 = On, obtain the ATAN value of binary floating point (D1, D0) and store the binary floating point result in
(D11, D10).
