+
+.SH DESCRIPTION
+.sp
+.LP
+These functions return the integral value (represented as a \fBdouble\fR)
+nearest \fIx\fR in the direction of the current rounding mode.
+.sp
+.LP
+If the current rounding mode rounds toward negative infinity, \fBrint()\fR is
+equivalent to \fBfloor\fR(3M). If the current rounding mode rounds toward
+positive infinity, \fBrint()\fR is equivalent to \fBceil\fR(3M).
+.sp
+.LP
+These functions differ from the \fBnearbyint\fR(3M), \fBnearbyintf()\fR, and
+\fBnearbyintl()\fR functions only in that they might raise the inexact
+floating-point exception if the result differs in value from the argument.
+.SH RETURN VALUES
+.sp
+.LP
+Upon successful completion, these functions return the integer (represented as
+a double precision number) nearest \fIx\fR in the direction of the current
+rounding mode.
+.sp
+.LP
+If \fIx\fR is NaN, a NaN is returned.
+.sp
+.LP
+If \fIx\fR is \(+-0 or \(+-Inf, \fIx\fR is returned.
