Examples

>>> q = cf.isclose(9)
>>> q
<CF Query: (isclose 9)>
>>> q.setdefault(rtol=1e-5, atol=1e-08)
<CF Query: (isclose 9 rtol=1e-05 atol=1e-08)>

>>> q = cf.isclose(9, rtol=9e-9)
>>> q.setdefault(rtol=1e-5, atol=1e-08)
>>> q
<CF Query: (isclose 9 rtol=9e-09 atol=1e-08)>

>>> q = cf.lt(9) & (cf.eq(1) | cf.isclose(4, rtol=9e-9))
>>> q
<CF Query: [(lt 9) & [(eq 1) | (isclose 4 rtol=9e-09)]]>
>>> q.setdefault(rtol=1e-5, atol=1e-08)
>>> q
<CF Query: [(lt 9) & [(eq 1) | (isclose 4 rtol=9e-09 atol=1e-08)]]>
