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