cf.Data.allclose

Data.allclose(y, rtol=None, atol=None)

Returns True if two broadcastable arrays have equal values, False otherwise.

For numeric data arrays d.allclose(y, rtol, atol) is equivalent to (abs(d - y) <= ``atol + rtol*abs(y)).all(), otherwise it is equivalent to (d == y).all().

Parameters :

y : data_like

atol : float, optional

The absolute tolerance for all numerical comparisons, By default the value returned by the ATOL function is used.

rtol : float, optional

The relative tolerance for all numerical comparisons, By default the value returned by the RTOL function is used.

Returns :

out : bool

Examples

>>> d = cf.Data([1000, 2500], 'metre')
>>> e = cf.Data([1, 2.5], 'km')
>>> d.allclose(e)
True

>>> d = cf.Data(['ab', 'cdef'])
>>> d.isclose([[['ab', 'cdef']]])
True

>>> d.allclose(e)
True

>>> d = cf.Data([[1000, 2500], [1000, 2500]], 'metre')
>>> e = cf.Data([1, 2.5], 'km')
>>> d.allclose(e)
True

>>> d = cf.Data([1, 1, 1], 's')
>>> d.allclose(1)
True
