This instruction finds the hyperbolic cosine of the value in S and stores it in D. Hyperbolic cosine value=(e
1.
2. If the absolute value of the conversion result is larger than the value that can be represented by floating-point
numbers, 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 that can be represented by floating-point
numbers, the value in D is 16#FF800000, and SM601 is ON.
4. If the conversion result is zero, SM600 is ON.
Example
When X0.0 is ON, the instruction finds the hyperbolic cosine of the floating-point number in (D1, D0) and stores it
1.
in (D11, D10). The hyperbolic cosine value in (D11, D10) is a floating-point number.
