Parameters ---------- x : array_like Angles in degrees. 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 radians. See Also -------- rad2deg : Convert angles from radians to degrees. unwrap : Remove large jumps in angle by wrapping. Notes ----- ``deg2rad(x)`` is ``x * pi / 180``. Examples -------- >>> import mars.tensor as mt >>> mt.deg2rad(180).execute() 3.1415926535897931 """ op = TensorDeg2rad(**kwargs) return op(x, out=out, where=where)
