isequal | Component-wise compare of `x` == `y`.
isnotequal | Component-wise compare of `x` != `y`.
isgreater | Component-wise compare of `x` > `y`.
isgreaterequal | Component-wise compare of `x` >= `y`.
isless | Component-wise compare of `x` < `y`.
islessequal | Component-wise compare of `x` <= `y`.
islessgreater | Component-wise compare of (`x` < `y`) || (`x` > `y`).
isfinite | Test for finite value.
isinf | Test for positive or negative infinity.
isnan | Test for a NaN.
isnormal | Test for a normal value.
isordered | Test if arguments are ordered.
isunordered | Test if arguments are unordered.
signbit | Test for sign bit.
any | 1 if MSB in any component of `x` is set; else 0.
all | 1 if MSB in all components of `x` is set; else 0.
bitselect | Each bit of result is corresponding bit of `a` if corresponding bit of `c` is 0.
select | For each component of a vector type, result[`i`] = if MSB of `c`[`i`] is set ? `b`[`i`] : `a`[`i`] For scalar type, result = `c` ? `b` : `a`.

## Description

If an implementation extends this specification to support IEEE-754 flags or exceptions, then all built-in relational functions shall proceed without raising the `invalid` floating-point exception when one or more of the operands are NaNs.
