
The equation below is used to convert a radian into a degree.

S : Source (radian); D : Conversion result (degree)
Degree
＝
Radian×(180/
π
)

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.

SM1064 is the zero flag in an Ox motion subroutine, and SM968 is the
zero flag in O100.

SM1065 is the borrow flag in an Ox motion subroutine, and SM969 is the
borrow flag in O100.

SM1066 is the carry flag in an Ox motion subroutine, and SM970 is the
carry flag in O100.

When X0.0 is ON, the radian in (D1, D0) is converted into a degree, and
the conversion result is stored in (D11, D10). The degree in (D11, D10) is
a floating-point number.
