-.SH DESCRIPTION
-These functions round their argument to the nearest integer value,
-using the current rounding direction (see
-.BR fesetround (3)).
-.P
-Note that unlike the
-.BR rint (3)
-family of functions,
-the return type of these functions differs from
-that of their arguments.
-.SH RETURN VALUE
-These functions return the rounded integer value.
-.P
-If
-.I x
-is a NaN or an infinity,
-or the rounded value is too large to be stored in a
-.I long
-.RI ( "long long"
-in the case of the
-.B ll*
-functions),
-then a domain error occurs, and the return value is unspecified.
-.\" The return value is -(LONG_MAX - 1) or -(LLONG_MAX -1)
-.SH ERRORS
-See
-.BR math_error (7)
-for information on how to determine whether an error has occurred
-when calling these functions.
-.P
-The following errors can occur:
-.TP
-Domain error: \fIx\fP is a NaN or infinite, or the rounded value is too large
-.\" .I errno
-.\" is set to
-.\" .BR EDOM .
-An invalid floating-point exception
-.RB ( FE_INVALID )
-is raised.
-.P
-These functions do not set
-.IR errno .
-.\" FIXME . Is it intentional that these functions do not set errno?
