`Field.``exp`(bounds=True, i=False)

  The exponential of the data array.

  `log`

  Examples 1: |

      >>> g = f.exp()

  Parameters: | bounds: optional Ignored. i: `bool`, optional If True then update the field in place. By default a new field is created. In either case, a field is returned.
  Returns: | out: `cf.Field` The field with the exponential of data array values.
  Examples 2: |

      >>> f.data
      <CF Data: [[1, 2]]>
      >>> f.exp().data
      <CF Data: [[2.71828182846, 7.38905609893]]>

      >>> f.data
      <CF Data: [[1, 2]] 2>
      >>> f.exp().data
      <CF Data: [[7.38905609893, 54.5981500331]]>

      >>> g = f.exp(i=True)
      >>> g is f
      True

      >>> f.data
      <CF Data: [[1, 2]] kg m-1 s-2>
      >>> f.+name}()
      ValueError: Can't take exponential of dimensional quantities: <CF Units: kg m-1 s-2>
