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.
