Similarity Functions

Deterministic similarity and likeness functions

Name	Parameters	Returns	Description
Similarity.Centered	(decimal value, decimal center, decimal radius)	decimal	Returns similarity of a value relative to a center and radius.
Similarity.InverseDistance	(decimal a, decimal b)	decimal	Returns similarity as inverse distance (1 / (1 + distance)).
Similarity.IsDissimilar	(decimal a, decimal b, decimal tolerance)	bool	Returns true if values differ beyond tolerance.
Similarity.IsSimilar	(decimal a, decimal b, decimal tolerance)	bool	Returns true if values are similar within tolerance.
Similarity.Linear	(decimal a, decimal b, decimal tolerance)	decimal	Returns a linear similarity score based on tolerance (1 = identical).
Similarity.Normalized	(decimal a, decimal b, decimal maxRange)	decimal	Returns normalized similarity based on max range.
Similarity.Percent	(decimal a, decimal b)	decimal	Returns similarity as a percentage (0..100).
Similarity.Ratio	(decimal a, decimal b)	decimal	Returns similarity ratio between two values.
Similarity.Score	(decimal a, decimal b, decimal maxDistance)	decimal	Returns similarity score given a maximum distance.
