Description
any returns 1 if the most significant bit in any component of
x is set; otherwise returns 0.
all returns 1 if the most significant bit in al components of
x is set; otherwise returns 0.
Notes
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 argument type igentype refers to signed integer types, i.e. char,
charn, short, shortn,
int, intn, long, and
longn.
