Explanation:
1. Hyperbolic tangent value=(e
2. If the conversion result is 0, SM600 is ON.
Example:
1. When X0.0 is ON, the hyperbolic tangent of the floating-point number in (D1, D0) is stored in
(D11, D10). The hyperbolic tangent value in (D11, D10) is the floating-point number.
2. 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.
