The “standard_name” and “long_name” properties are removed from the result.

Examples
>>> print(f.array) [[0.5 0.7] [0.9 1.1]] >>> g = f.arctanh() >>> g.Units <Units: radians> >>> print(g.array) [[0.54930614 0.86730053] [1.47221949 nan]]
>>> print(f.array) [1.2 1.0 0.8 0.6 ] >>> f.arctanh(inplace=True) >>> print(f.array) [nan inf 1.0986122886681098 0.6931471805599453 ] >>> f.masked_invalid(inplace=True) >>> print(f.array) [  1.0986122886681098 0.6931471805599453 ]
