Unity unit for Angle ?

I have been looking around but I can’t seem to find out what is the unit for Unity angle/ rotation. I need to do some computing, but I don’t know if rad or degree or some other things is the unit for Angle in Unity. A LOT OF THANKS

it tells you clearly in each piece of documentation.

For example,

“Returns the sine of angle f in radians.”

Also notice:

For example

function sine( D:float )
	return Mathf.Sin( D * Mathf.Deg2Rad );
function cosine( D:float )
	return Mathf.Cos( D * Mathf.Deg2Rad );
