Units are ignored in the calculation. The result has units of radians.
The “standard_name” and “long_name” properties are removed from the result.
New in version 3.2.0.

Examples
>>> print(f.array) [[0.5 0.7] [0.9 1.1]] >>> g = f.arccosh() >>> g.Units <Units: radians> >>> print(g.array) [[ nan nan] [ nan 0.44356825]]
>>> print(f.array) [1.2 1.0 0.8 0.6 ] >>> f.arccosh(inplace=True) >>> print(f.array) [0.6223625037147786 0.0 nan nan ] >>> f.mask_invalid(inplace=True) >>> print(f.array) [0.6223625037147786 0.0   ]
