Symbol:
S
：
Data source (radian) Double word
D
：
Conversion result (Degree) Double word
Explanation:
1. The equation below is used to convert radians into degrees.
2. Degree＝Radian×(180/π).
3. 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#7F7FFFFF.
4. 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#7F7FFFFF.
5. If the conversion result is 0, SM600 is ON.
Example:
When X0.0 is ON, the radian in (D1, D0) is converted into the degree, and the conversion result is
stored in (D11, D10). The degree in (D11, D10) is the floating-point number.

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.
