/// \brief Abstract base class for elementwise unary arithmetic operations, i.e.,
///        operations where the same scalar arithmetic operation is applied to each
///        element.
///
/// For example, if the underlying operation (determined by the subclass) is
/// \f$\mathit{op}(x)\f$, the input tensor \f$[[x,y],[z,w]]\f$ will be mapped to
/// \f$[[\mathit{op}(x),\mathit{op}(y)],[\mathit{op}(z),\mathit{op}(w)]]\f$.
///
/// ## Inputs
///
/// |       | Type                              | Description                                                              |

/// | `arg` | \f$N[d_1,\dots,d_n]~(n \geq 0)\f$ | A tensor of any shape. The element type \f$N\f$ may be any numeric type. |
