Parameters ---------- x : array_like Angle in radians. out : Tensor, None, or tuple of Tensor and None, optional A location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or `None`, a freshly-allocated tensor is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs. where : array_like, optional Values of True indicate to calculate the ufunc at that position, values of False indicate to leave the value in the output alone. **kwargs Returns ------- y : Tensor The corresponding angle in degrees. See Also -------- deg2rad : Convert angles from degrees to radians. Notes ----- rad2deg(x) is ``180 * x / pi``. Examples -------- >>> import mars.tensor as mt >>> mt.rad2deg(mt.pi/2).execute() 90.0 """ op = TensorRad2deg(**kwargs) return op(x, out=out, where=where)
