float       nearbyintf( float arg );
(since C99)
double      nearbyint( double arg );
(since C99)
long double nearbyintl( long double arg );
(since C99)

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.
