Format column of floats containing NaN values

I have dataframe columns with floats and NaN's and need to format some of them with 0 decimal places and some of them two decimal places. Currently to get the 0 decimal places I am using the code below:

    df['myCol'] = df['myCol'].fillna(-1)
    df['myCol'] = df['myCol'].astype(int)
    df['myCol'] = df['myCol'].astype(str)
    df['myCol'] = df['myCol'].replace('-1', '')

Is there a faster way to do this and what is the best way for formatting the columns where two decimal places are necessary?

You could use df.round()

df['myCol'] = df['myCol'].round(decimals=2)
