Python Pandas DataFrame Rounding Of Big Fraction Values

How to round off big fraction values of a pandas DataFrame.I want to round off the 'Gaps between male and female score' column of the given Dataframe image. I have tried following:

Solution 1:

Considering some initial rows of your dataframe,

    Year    Score
0   1990    1.00378
1   1992    2.37824
2   2000    2.51302
3   2003    2.96111

Now, if you want to round score to int, do this,

df['Score'] = df['Score'].astype(int)
df

Output:

    Year    Score
0   1990    1
1   1992    2
2   2000    2
3   2003    2

And, if you want to round upto some decimal digits say upto 2-digits. Note: you can round upto as many digits as you want by passing required value to round().

df['Score'] = df['Score'].round(2)
df

Output:

  Year  Score
0   1990    1.00
1   1992    2.38
2   2000    2.51
3   2003    2.96

If you want to round by ceil or by floor, then use np.ceil(series) or np.floor(series) respectively.
