gentype
bitselect
(
| gentype a, |
gentype b, | |
gentype c) |
Each bit of result is corresponding bit of a
if corresponding bit of c
is 0. Otherwise it is the corresponding bit of b
.
The relational and equality operators (<, <=, >, >=, !=, ==) can be used with scalar and vector built-in types and produce a scalar or vector signed integer result respectively.
The built-in relational functions can be used with built-in scalar or vector types as
arguments and return a scalar or vector integer result. If an implementation extends this
specification to support IEEE-754 flags or exceptions, then all built-in Relational
shall proceed without raising the invalid
floating-point exception when one or more of the
operands are NaNs.
The built-in relational functions are extended with
cl_khr_fp64
to include appropriate versions of functions that take double, and
double{2|3|4|8|16} as arguments and return values. They are also extended with
cl_khr_fp16 to include appropriate versions
of functions that take half, and half{2|3|4|8|16} as arguments and return values.
The relational and equality operators (<, <=, >, >=, !=, ==) can be used
with doublen
vector types and shall produce a vector
longn
result.
The argment type gentype can be char,
charn
,uchar, ucharn
,
short, shortn
, ushort,
ushortn
, int, intn
,
uint, uintn
, long,
longn
, ulong, ulongn
,
float, and floatn
