Arrotonda il virgola mobile arg argomento in un valore intero in formato di virgola mobile, utilizzando la modalità corrente di arrotondamento. Se il risultato è diverso da arg (cioè, arg non era già un valore intero), la virgola mobile FE_INEXACT eccezione viene sollevata.
Original:
Rounds the floating-point argument arg to an integer value in floating-point format, using the current rounding mode. If the result differs from arg (i.e., arg was not an integer value already), the floating-point exception FE_INEXACT is raised.

[modifica] Note

L'unica differenza tra nearbyint e rint è che rint può sollevare in virgola mobile eccezione FE_INEXACT, pur non essendo mai nearbyint solleva.
Original:
The only difference between nearbyint and rint is that rint may raise the FE_INEXACT floating-point exception, while nearbyint never raises it.
