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.

### [editar]Notas

A única diferença entre nearbyint e rint é que rint pode aumentar o FE_INEXACT exceção de ponto flutuante, sem nunca nearbyint levanta-lo.
Original:
The only difference between nearbyint and rint is that rint may raise the FE_INEXACT floating-point exception, while nearbyint never raises it.
