The rint(),
rintf(), and rintl()
functions return the integral value nearest to x
according to the prevailing rounding mode.
The nearbyint(),
nearbyintf(), and
nearbyintl() functions do the same, but without
raising the “inexact” floating-point exception.
A rint() function appeared in
Version 6 AT&T UNIX.
