Processing details
• These instructions convert the unit of the measure of angle from the radian specified by (s) to the degree, and store the
angle in degrees in the device number specified by (d).
• Unit conversion from the radian to the degree is performed as follows.
• If the operation result is -0 or an underflow occurs, the operation result turns out to 0.
• When an input value is set using the engineering tool, a rounding error may occur. Refer to the following for the precautions
on setting input values using the engineering tool.
