Examples:
>>> print(d.array) [[0.5 0.7] [0.9 1.1]] >>> e = d.arctan() >>> e.Units <Units: radians> >>> print(e.array) [[0.46364761 0.61072596] [0.7328151 0.83298127]]
>>> print(d.array) [1.2 1.0 0.8 0.6 ] >>> d.arctan(inplace=True) >>> print(d.array) [0.8760580505981934 0.7853981633974483 0.6747409422235527 0.5404195002705842 ]
