ENH: add support for .ceil() and .floor() for series/frame

[auderson]

Feature Type

• Adding new functionality to pandas

• Changing existing functionality in pandas

• Removing existing functionality in pandas

Problem Description

Currently ceil and floor is achieved by codes like:

df = df.mask(df > 0, 0)

this can be slow in terms of performance compared to native methods like np.ceil and np.floor

Feature Description

Add new .ceil and .floor method, possibly using np.ceil and np.floor

Alternative Solutions

df = pd.DataFrame(np.ceil(df.values, 0), index=df.index, columns=df.columns)
