| Name| Description
| xref:BloombergLP/bdlb/Float/Classification.adoc[`Classification`] 
| 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;
| xref:BloombergLP/bdlb/Float/FineClassification.adoc[`FineClassification`] 
| Fine&hyphen;grained classifications for floating&hyphen;point numbers that distinguish positive numbers from negative numbers and quiet NaNs from signaling NaNs&period; Every floating&hyphen;point number belongs to exactly one of these classifications&period;
