Operands:
S
: Source (radian) D: Result (angle)
Explanations:
1. See the specifications of each model for their range of use.
2. Flags: M1020 (zero flag); M1021 (borrow flag); M1022 (carry flag)
3. Degree = radian × (180/
π
)
4. If the absolute value of the result ＞ maximum floating point available, the carry flag M1022 = On.
5. If the absolute value of the result ＜ minimum floating point available, the borrow flag M1021 = On.
6. If the result = 0, the zero flag M1020 = On.
Program Example:
When X0 = On, designate the angle of binary floating point (D1, D0). Convert the radian into angle and store the
result in binary floating point in (D11, D10).
