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. .SH ATTRIBUTES .sp .LP See \fBattributes\fR(7) for descriptions of the following attributes: .sp .TS tab( ) box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) .
