cf.Data.isclose¶

Data.
isclose
(y, rtol=None, atol=None)[source]¶ Return where data are elementwise equal within a tolerance.
Two real numbers
x
andy
are considered equal ifxy<=atol+rtoly
, whereatol
(the tolerance on absolute differences) andrtol
(the tolerance on relative differences) are positive, typically very small numbers. See the atol and rtol parameters.For numeric data arrays,
d.isclose(e, rtol, atol)
is equivalent toabs(d  e) <= atol + rtol*abs(e)
, otherwise it is equivalent tod == e
. Parameters
 y: data_like
The array to compare.
 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
bool
A boolean array of where the data are close to y.
Examples
>>> d = cf.Data([1000, 2500], 'metre') >>> e = cf.Data([1, 2.5], 'km') >>> print(d.isclose(e).array) [ True True]
>>> d = cf.Data(['ab', 'cdef']) >>> print(d.isclose([[['ab', 'cdef']]]).array) [[[ True True]]]
>>> d = cf.Data([[1000, 2500], [1000, 2500]], 'metre') >>> e = cf.Data([1, 2.5], 'km') >>> print(d.isclose(e).array) [[ True True] [ True True]]
>>> d = cf.Data([1, 1, 1], 's') >>> print(d.isclose(1).array) [ True True True]
