Debugging broken tests can be very tricky

	Can you spot a problem in the code?

	np.testing.assert_almost_equal(A, B, decimal=7)

	Error log:
	-------------------------------------------------------------------------------
	AssertionError:
	Arrays are not almost equal to 7 decimals

	(mismatch 18.75%)

	// Simple tool to store all integers which are missing in the float representation.
	//
	// Missing means here that if you convert integer into float and then back into
	// integer you will not get the same integer. This experiment reveals that for
	// 96.5% of all integers n != int(float(n))
	//
	// It appears that missing integers go in blocks of length 2, 6, 14, 30, 62
	// and 126 of consecutive numbers (8388608 blocks of each type).
	// And there is one single integer -33554431 who stands apart.
