8 Application Instructions API 100-149 API 138 Operands: S : Source value (binary floating point) D : TANH result 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. TANH value=(e s -e -s )/(e s +e -s ) . The result is stored in D . Program Example: 1. When X0 = On, obtain the TANH value of binary floating point (D1, D0) and store the binary floating point result in (D11, D10). X0 D1 D0 binary floating point D11 D10 TANH value binary floating point 2. If the absolute value of the result > maximum floating point available, the carry flag M1022 = On. 3.
If the absolute value of the result < minimum floating point available, the borrow flag M1021 = On. 4. If the result = 0, the zero flag M1020 = On. Remarks: For floating point operations, see “5.3 Handling of Numeric Values”.
