Operands:
S : data source (radians) D : Destination result (degrees)
Description:
1. This instruction uses the following formula to convert radians to degrees:
Degrees
＝
Radians
×
(180/
π
)
2. Flags: M1020 Zero flag, M1021 Borrow flag and M1022 Carry flag.
If the absolute value of the result is larger than the maximum floating point value, the carry flag
M1022= ON.
If absolute value of the results is less than the minimum floating point value, the borrow flag
M1021= ON.
If the conversion result is 0, zero flag M1020= ON.
Program Example:
When X0= ON, convert the degrees value of the binary floating point in D1/D0 to radians and save
the result in D11/D10 The result is binary floating point
.
