De numpy.round_() är en matematisk funktion som avrundar en matris till det givna antalet decimaler.
Syntax : numpy.round_(arr, decimaler = 0, ut = Ingen)
Parametrar:
array: [array_like] Ingångsmatris.
decimal: [int, valfritt] Decimaler vill vi runda av.
Standard = 0. Vid -ve decimal specificerar den n0. av positioner till vänster om decimalkomma.
bash variabelut: [frivillig] Utdata resulterade array
