De numpy.round_() is een wiskundige functie die een array afrondt op het opgegeven aantal decimalen.
Syntaxis: numpy.round_(arr, decimalen = 0, out = Geen)
Parameters:
reeks: [array_like] Invoerarray.
decimaal: [int, optioneel] Decimalen die we willen afronden.
Standaard = 0. In het geval van -ve decimaal, specificeert dit de n0. aantal posities links van de komma.
Hoe tekenreeks naar char te converterenuit : [optioneel] Uitvoer resulteerde array
Opbrengst :
An array with all array elements being rounded off, having same type as input.>
