atoti.math.floor()

atoti.math.floor(measure, /)

Return a measure equal to the largest integer <= to the passed measure.

Example

>>> 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.floor(m["C.SUM"])
>>> cube.query(m["C.SUM"], m["⌊C⌋"], levels=[l["City"]])
          C.SUM ⌊C⌋
City
Berlin    10.10  10
London    20.50  20
New York  30.70  30
Paris       .00   0
