Parameters ---------- x : array_like Input tensor 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 radian values. See Also -------- deg2rad : equivalent function Examples -------- Convert a degree array to radians >>> import mars.tensor as mt >>> deg = mt.arange(12.) * 30. >>> mt.radians(deg).execute() array([ 0. , 0.52359878, 1.04719755, 1.57079633, 2.0943951 , 2.61799388, 3.14159265, 3.66519143, 4.1887902 , 4.71238898, 5.23598776, 5.75958653]) >>> out = mt.zeros((deg.shape)) >>> ret = mt.radians(deg, out) >>> ret is out True """ op = TensorRadians(**kwargs) return op(x, out=out, where=where)
