8 Application Instructions API 100-149 API 116 Operands: S : Source (angle) D : Result (radian) Explanations: 1. See the specifications of each model for their range of use. 2. Flags: M1020 (zero flag); M1021 (borrow flag); M1022 (carry flag) 3. Radian = degree Ч ( π /180) 4. If the absolute value of the result ＞ maximum floating point available, the carry flag M1022 = On. 5. If the absolute value of the result ＜ minimum floating point available, the borrow flag M1021 = On. 6. If the result = 0, the zero flag M1020 = On. Program Example: When X0 = On, designate the degree of binary floating point (D1, D0).
Convert the angle into radian and store the result in binary floating point in (D11, D10). X0 Angle binary floating point D 11 D 10 binary floating point Radian ( 180) / X degree Remarks: For floating point operations, see “5.3 Handling of Numeric Values”.
