Function
Binary oating-point degrees are converted to radians. The calculation formula is [Angle in radians = Angle
in degrees x π/180].
Example 1:
M10
ǒDRAD D0 D2Ǔ
S D
M11
When M10 = ON, degree-to-radian conversion is
performed on the binary floating-point number in (D1, D0).
The result is stored in (D3, D2).
ǒDRADP D10 D12Ǔ
Example 2:
M10
ǒMOV K90 D0Ǔ
When M10 switches from OFF to ON, the value 90 is assigned to D0.
The integer in D0 is converted to a floating-point number,
which is then assigned to (D3, D2). Degree-to-radian conversion is
performed on (D3, D2) and the result is assigned to (D5, D4).
The final value in (D3, D2) is
æ/2, that is, 1.570796.

ǒDRAD D2 D4Ǔ
