# atoti.math.ceil()

### atoti.math.ceil(measure, /)

Return a measure equal to the smallest integer that is >= to the passed measure.

### Example

```pycon theme={"languages":{"custom":["/engine/python-sdk/0.9/languages/pycon.tmLanguage.json"]}}
>>> df = pd.DataFrame(
...     columns=["City", "A", "B", "C", "D"],
...     data=[
...         ("Berlin", 15.0, 10.0, 10.1, 1.0),
...         ("London", 24.0, 16.0, 20.5, 3.14),
...         ("New York", -27.0, 15.0, 30.7, 10.0),
...         ("Paris", 0.0, 0.0, 0.0, 0.0),
...     ],
... )
>>> table = session.read_pandas(df, keys={"City"}, table_name="Math")
>>> cube = session.create_cube(table)
>>> l, m = cube.levels, cube.measures
>>> m["⌈C⌉"] = tt.math.ceil(m["C.SUM"])
>>> cube.query(m["C.SUM"], m["⌈C⌉"], levels=[l["City"]])
          C.SUM ⌈C⌉
City
Berlin    10.10  11
London    20.50  21
New York  30.70  31
Paris       .00   0
```
