numpy.round_() i Python
Det numpy.round_() er en matematisk funktion, der afrunder en matrix til det givne antal decimaler.
Syntaks: numpy.round_(arr, decimaler = 0, ud = Ingen)
Parametre:
array: [array_like] Input array.
decimal: [int, valgfri] Decimaler vil vi gerne runde af.Standard = 0. I tilfælde af -ve decimal angiver den n0. af positioner til venstre for decimaltegnet.
ud: [valgfri] Output resulterede matrix
Vend tilbage :
An array with all array elements being rounded off, having same type as input.
