Learn how to use numpy.round function to evenly round array elements to a given number of decimals. See parameters, output, examples, and notes on accuracy and performance.
8 mar 2024 · The numpy.round_ () is a mathematical function that rounds an array to the given number of decimals. Syntax : numpy.round_ (arr, decimals = 0, out = None) Parameters : array : [array_like] Input array. decimal : [int, optional] Decimal places we want to round off. Default = 0.
You can use set_printoptions and a custom formatter to fix this and get a more numpy-esque printout with fewer decimal places: >>> np.set_printoptions(formatter={'float': "{0:0.2e}".format}) >>> print(arr) [2.92e+00 -1.57e-03 4.82e-08 1.93e-12]
