Difference between modes a, a+, w, w+, and r+ in built-in open function?
...
I think this is important to consider for cross-platform execution, i.e. as a CYA. :)

python numpy machine epsilon
... Python's builtin float. Python floats are 64-bit (C double) on almost all platforms. float and np.float64 therefore usually have equivalent precision, and for most purposes you can use them interchangeably. However they aren't identical - np.float64 is a numpy-specific type, and an np.float64 scala...
