Parameters:
series:pd.Series
Only pandas.Series
value:Union[float,int]
the value you want to have the closest neighbours from
convertdtypes:bool
converts string numbers to numbers
(default=False)
accept_exact_match:bool
example:
True: if you are passing 72, and 72 is in the Series, the minimum and maximum values will be all the same, that means: 72
False: All cells with 72 are excluded, and you won't see 72 in the results
(default=False)
Returns:
tuple
