numpy.floor(x, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj]) = <ufunc 'floor'>
Return the floor of the input, elementwise.
The floor of the scalar x
is the largest integer i
, such that i <= x
. It is often denoted as .
Parameters: 


Returns: 

Some spreadsheet programs calculate the “floortowardszero”, in other words floor(2.5) == 2
. NumPy instead uses the definition of floor
where floor(2.5) == 3
.
>>> a = np.array([1.7, 1.5, 0.2, 0.2, 1.5, 1.7, 2.0]) >>> np.floor(a) array([2., 2., 1., 0., 1., 1., 2.])
