  "behaviors": [
    "Operates element-wise on scalars, vectors, matrices, and N-D tensors.",
    "Integer and logical inputs are promoted to double precision before conversion.",

      "question": "Does `rad2deg` preserve array shape?",
      "answer": "Yes. Each element is converted independently and the original shape is preserved."
