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

4. The decimal floating point of the SIN value designated by S should be within -1.0 ~ +1.0. If the value falls without
the range, M1067 and M1068 will be On without performing any action.
5. If the result = 0, M1020 = On.
Program Example:
When X0 = On, obtain the ASIN value of binary floating point (D1, D0) and store the binary floating point result in (D11,
D10).
