The relational and equality operators (<, <=, >, >=, !=, ==) can
be used with halfn vector types
and shall produce a vector short* n* result.

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 double* n* vector types and shall produce a vector
long

`n`

The function returns a 0 if the specified relation is `false`

and a
1 if the specified relation is `true`

for scalar argument types. These
functions shall return a 0 if the specified relation is `false`

and a - 1
(i.e. all bits set) if the specified relation is `true`

for vector argument types.
