.BI "int all(igentype\ " "x" ");"
.SH "DESCRIPTION"
.PP
\fBany\fR
returns 1 if the most significant bit in any component of
\fIx\fR
is set; otherwise returns 0\&.
.PP
\fBall\fR
returns 1 if the most significant bit in all components of
\fIx\fR
is set; otherwise returns 0\&.
.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 argument type
\fBigentype\fR
refers to signed integer types, i\&.e\&.
\fBchar\fR,
\fBchar\fR\fB\fIn\fR\fR,
\fBshort\fR,
\fBshort\fR\fB\fIn\fR\fR,
\fBint\fR,
\fBint\fR\fB\fIn\fR\fR,
\fBlong\fR, and
\fBlong\fR\fB\fIn\fR\fR\&.
\fIn\fR is 2, 3, 4, 8, or 16\&.
