.SH "DESCRIPTION"
.PP
Returns the component\-wise compare of
\fIx\fR
>=
\fIy\fR\&.
.PP
.SH "NOTES"
.PP
If an implementation extends this specification to support IEEE\-754 flags or exceptions, then all built\-in relational functions shall proceed without raising the
\fIinvalid\fR
floating\-point exception when one or more of the operands are NaNs\&.
.PP
The built\-in relational functions are extended with
\fBcl_khr_fp16\fR(3clc)
to include appropriate versions of functions that take
\fBhalf\fR, and
\fBhalf{2|3|4|8|16}\fR
as arguments and return values\&.
.PP
The function returns a 0 if the specified relation is
\fBfalse\fR
and a 1 if the specified relation is
\fBtrue\fR
for scalar argument types\&. These functions shall return a 0 if the specified relation is
\fBfalse\fR
and a \- 1 (i\&.e\&. all bits set) if the specified relation is
\fBtrue\fR
for vector argument types\&.
.PP
The relational functions
\fBisequal\fR,
\fBisgreater\fR,
\fBisgreaterequal\fR,
\fBisless\fR,
\fBislessequal\fR, and
\fBislessgreater\fR
always return 0 if either argument is not a number (NaN)\&.
\fBisnotequal\fR
returns 1 if one or both arguments are not a number (NaN) and the argument type is a scalar and returns \-1 if one or both arguments are not a number (NaN) and the argument type is a vector\&.
