struct comp_metadata §

For use with min_with_metadata and max_with_metadata while computing min/max of a number represented through multiple words. The struct represents the result of the computation on the “previous” word while progressing from the most significant word to the least.

Fields

  • bool all_previous_words_eq §

    The incoming metadata for comparing kth word (from the most significant word) of inputs a_words and b_words, will have its value equal to true if for all i in range [0, k), a_words[i] == b_words[i]. Note 0 here represents the most significant words’ position. Initialize this to true for first invocation to min_with_metadata or max_with_metadata

  • bool select_a_words_on_prevnoteq §

    The incoming metadata will have a valid value for this iff incoming all_previous_words_eq == false. Once all_previous_words_eq is false, this variable represents that for all following words, words of a_words should be selected for the result. Can be initialized to either true or false.
