Explanation
 The equation below is u
sed to convert a degree into a radian.
 S: Source (degree); D: Conversion result (radian)
Radian＝Degree×(π /180)
 If the absolute value of a conversion result is greater than the maximum
floating-point value available, a carry flag will be ON.
 If the absolute value of a conversion reuslt is less than the minimum
floating-point value available, a borrow flag will be ON.
 If a converseion result is 0, a zero flag will be ON.
Example

When X0 is ON, the degree in (D1, D0) is converted into a radian, and the
conversion result is stored in (D11, D10). The radian in (D11, D10) is a binary
floating-point value.
