      Parameters
      ----------
      x
          Input array.
      approximate
          Whether to approximate, default is ``True``. An approximation is always used if
          the input array is complex.
      complex_mode
          optional specifier for how to handle complex data types. See
          ``ivy.func_wrapper.handle_complex_input`` for more detail.
      out
          optional output array, for writing the result to. It must have a shape that the
          inputs broadcast to.
  
      Returns
      -------
      ret
          The input array with gelu applied element-wise.
  
      Examples
      --------
      With :class:`ivy.Array` input:
  
      >>> x = ivy.array([-1.2, -0.6, 1.5])
      >>> y = ivy.gelu(x)

      >>> x = ivy.native_array([-1.3, 3.8, 2.1])
      >>> y = ivy.gelu(x)
      >>> y
      ivy.array([-0.126, 3.8, 2.06])
  
      With :class:`ivy.Container` input:
  
      >>> x = ivy.Container(a=ivy.array([1., 2.]), b=ivy.array([-0.9, -1.]))
      >>> y = ivy.gelu(x)
