Arredonda o arg argumento de ponto flutuante para um valor inteiro no formato de ponto flutuante, usando o modo de arredondamento atual. Se o resultado difere do arg (isto é, não foi arg um valor inteiro já), o FE_INEXACT exceção de ponto flutuante é levantada.
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.

Original:
The only difference between nearbyint and rint is that rint may raise the FE_INEXACT floating-point exception, while nearbyint never raises it.
