Overview
The rint(), rintf(), and rintl() functions return the integral value nearest to x according to the prevailing rounding mode. These functions raise an inexact exception when the original argument is not an exact integer.
The nearbyint(), nearbyintf(), and nearbyintl() functions perform the same operation, except that they do not raise an inexact exception.
