Function
Binary oating-point radians are converted to degrees. The calculation formula is [Angle in degrees = Angle
in radians x 180/π].
Example 1:
M10
ǒDDEG D0 D2Ǔ
S D
M11
When M10 = ON, radian-to-degree conversion is performed
on the binary floating-point number in (D1, D0).
The result is stored in (D3, D2).
ǒDDEGP D10 D12Ǔ
Example 2:
M10
ǒDDEG D0 D2Ǔ
Assume that the value in (D1, D0) is 3.1415926. When M10
switches from OFF to ON, the value in (D3, D2) is 180.
After the floating-point number is converted to an integer,
the value in (D5, D4) is 180.
