Rounds the floating-point argument arg to an integer value in floating-point format, using the current rounding mode.

Contents

Parameters

arg - floating point value

Return value

The integer result of rounding arg

Notes

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