Pandas DataFrame - round() function: The round() function is used to round a DataFrame to a variable number of decimal places.
I would expect everything to be rounded to 2 decimal places, the way thefloat64(f64), andfloat(f) datatypes are in the example above. I would also expect that boolean indexing works within the range specified, according to what that dataframe shows as its values when printed. ...
