Operations returning logical values
Mind that in SIMD context these functions DO NOT return boolean but logical values that is an internal representation of a vector of truth values that can be handled by the function of the previous section logical operations).
The set of functions is quite exhaustive. Peculiarly all comparison are treated with their negations and decorations as sometime architectures provide specific intrinsics and also because floating Nan values must be taken into account more easily.
Supplementary comparisons functions take the bit of sign of zero into account, namely is_eqpz, is_eqmz, is_negative, is_positive
