Using np.isclose #2

Question Q6.1.8

Explain why the following evaluates to True even though the two approximations to $\pi$ differ by more than $10^{-16}$:

In [x]: np.isclose(3.1415926535897932, 3.141592653589793, atol=1.e-16, rtol=0)
Out[x]: True

whereas this statement works as expected:

In [x]: np.isclose(3.14159265358979, 3.1415926535897, atol=1.e-14, rtol=0)
Out[x]: False
