For a given precision p >= 1, this rounds the number to p significant digits and then formats the result in either fixed-point format or in scientific notation, depending on its magnitude. my attempt at a solution. The API is composed of 5 relevant functions, available directly from the pandas namespace:. However, occasional I'm curious, whether there is any way to print formatted numpy.arrays, e.g., in a way similar to this:. The modified regular expression seemed to behave correctly in all test cases I could come up with. If False, then scientific notation is used when absolute value of the smallest number is < 1e-4 or the ratio of the maximum absolute value to the minimum is > 1e3.
