numpy.round_() Python

The numpy.round_() ir matemātiska funkcija, kas noapaļo masīvu līdz noteiktajam decimāldaļu skaitam.

Sintakse : numpy.round_(arr, decimālzīmes = 0, out = nav)
Parametri:
masīvs: [masīvs_līdzīgs] Ievades masīvs.
decimālzīme: [int, neobligāti] Decimālzīmes, kuras vēlamies noapaļot.



Noklusējums = 0. Ja decimālskaitlis ir -ve, tas norāda n0. pozīcijām pa kreisi no komata.

kaudze un kaudze šķirot

ārā: [neobligāti] Izvades rezultātā iegūtais masīvs

Atgriešanās:



 An array with all array elements being rounded off, having same type as input.>
