# cf.List.arccos¶

List.arccos(*args, **kwargs)[source]

Take the trigonometric inverse cosine of the data element- wise.

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.

Parameters
inplace: bool, optional

If True then do the operation in-place and return None.

Returns
List or None

The construct with the trigonometric inverse cosine of data values. If the operation was in-place then None is returned.

Examples:

>>> print(f.array)
[[0.5 0.7]
[0.9 1.1]]
>>> g = f.arccos()
>>> g.Units

>>> print(f.array)
