Explanation:
1. Hyperbolic cosine value=(e
2. If the absolute value of the conversion result is larger than the value which can be represented
by the maximum floating-point number, the value in D is 16#7F800000, and SM602 is ON.
3. If the absolute value of the conversion result is less than the value which can be represented
by the minimum floating-point number, the value in D is 16#FF800000, and SM601 is ON.
4. If the conversion result is 0, SM600 is ON.
Example:
1. When X0.0 is ON, the hyperbolic cosine of the floating-point number in (D1, D0) is stored in
(D11, D10). The hyperbolic cosine value in (D11, D10) is the floating-point number.
2. If the absolute value of the conversion result is larger than the value which can be represented
by the maximum floating-point number, SM602 is ON.
3. If the absolute value of the conversion result is less than the value which can be represented
by the minimum floating-point number, SM601 is ON.
4. If the conversion result is 0, SM600 is ON.
Additional remark:
If the value in S exceeds the range of values which can be represented by the floating-point
numbers, the instruction is not executed, SM0 is ON, and the error code in SR0 is 16#2013.
