These papers were matched to number systems and data representation automatically, by keyword patterns in their questions and mark schemes. A hand-check of 65 randomly chosen matches, read against the source question papers, found 53 that genuinely assess the topic and 12 that do not — 81.5% (95% confidence interval 70.4–89.1%). That is a good way to find practice on a topic, not proof a paper covers it, and a paper missing from this list may still assess it. A separate check found real papers that assess a topic without being tagged for it.
