This operation puts the calculator in radians mode. What this means is that any other operations which operates on angles (like trig functions), the angle is assumed to be expressed in radians. Also, operations which return an angle will return an angle expressed in radians. Note that if the input or output value is complex, it is always assumed to be expressed in radians, regardless of whether radian mode is on or not.
