-.PP
+.P
Note that unlike the
.BR rint (3)
family of functions,
that of their arguments.
.SH RETURN VALUE

-.PP
+.P
If
.I x
is a NaN or an infinity,
.BR math_error (7)
for information on how to determine whether an error has occurred
when calling these functions.
-.PP
+.P
The following errors can occur:
.TP
Domain error: \fIx\fP is a NaN or infinite, or the rounded value is too large
An invalid floating-point exception
.RB ( FE_INVALID )
is raised.
-.PP
+.P
These functions do not set
.IR errno .
.\" FIXME . Is it intentional that these functions do not set errno?
