Operands:
S: Source device (radian) D: Conversion result (degree)
Explanation
1. Use the following formula to convert radian to degree:
Degree ＝ Radian × (180/π)
Flags: M1020 Zero flag, M1021 Borrow flag and M1022 Carry flag.
If the absolute value of the result exceeds the max. floating point value, carry flag M1022 = ON.
If the absolute value of the result is less than the min. floating point value, borrow flag M1021 = ON.
If the conversion result is 0, zero flag M1020 = ON.
Program Example:
When X0 = ON, convert the radian of the binary floating point in (D1, D0) to degree and save the
binary floating point result in (D11, D10).
