python numpy machine epsilon

An easier way to get the machine epsilon for a given float type is to use np.finfo():

print(np.finfo(float).eps) # 2.22044604925e-16 print(np.finfo(np.float32).eps) # 1.19209e-07

Another easy way to get epsilon is:

In [1]: 7./3 - 4./3 -1 Out[1]: 2.220446049250313e-16
