Definitions

In plain terms

In HMA it is doubled before the full-length WMA is subtracted.

Technical

The implementation must state how n/2 is rounded, validate a positive result, and inherit WMA readiness and missing rules.

Scope

Half-length is derived from n and is not always an exact integer.

Examples

  • A governed lesson uses Half-Length WMA only with declared inputs, timing, parameters, and edge-case behavior.

Common misconceptions

  • Half-length is derived from n and is not always an exact integer.
