pandas.Series.round — pandas 3.0.0.dev0+2100.gf496acffcc documentation (original) (raw)

Series.round(decimals=0, *args, **kwargs)[source]#

Round each value in a Series to the given number of decimals.

Parameters:

decimalsint, default 0

Number of decimal places to round to. If decimals is negative, it specifies the number of positions to the left of the decimal point.

*args, **kwargs

Additional arguments and keywords have no effect but might be accepted for compatibility with NumPy.

Returns:

Series

Rounded values of the Series.

Notes

For values exactly halfway between rounded decimal values, pandas rounds to the nearest even value (e.g. -0.5 and 0.5 round to 0.0, 1.5 and 2.5 round to 2.0, etc.).

Examples

s = pd.Series([-0.5, 0.1, 2.5, 1.3, 2.7]) s.round() 0 -0.0 1 0.0 2 2.0 3 1.0 4 3.0 dtype: float64
