Operands:
S
: Source (angle)
D
: Result (radian)
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. Radian = degree × (
π
/180)
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 degree of binary floating point (D1, D0). Convert the angle into radian and store the
result in binary floating point in (D11, D10).
