Basic classifications for floating&hyphen;point numbers&period; Every floating&hyphen;point number belongs to exactly one of these classifications&period; However, the enumerated values have disjoint bit&hyphen;patterns to make it easy to create a &quot;set&quot; of classifications using bit&hyphen;wise OR&period;
