.Sh DESCRIPTION
The
-.Fn rint
-function returns the integral value (represented as a double precision number)
-nearest to
+.Fn rint ,
+.Fn rintf ,
+and
+.Fn rintl
+functions return the integral value nearest to
.Fa x
according to the prevailing rounding mode.
+.Pp
The
-.Fn rintf
-function is a single precision version of
-.Fn rint .
-The
-.Fn rintl
-function is an extended precision version of
-.Fn rint .
+.Fn nearbyint ,
+.Fn nearbyintf ,
+and
+.Fn nearbyintl
+functions return the integral value nearest to
+.Fa x
+according to the prevailing rounding mode, and without raising the
+.Dq inexact
+floating-point exception.
