SimilarityScore

SimilarityScore(string1, string2, ignoreCase): float

Calculates a similarity score between two strings using Levenshtein distance.

Added in version 6.0

Table 1. Parameters
string1	String	First string to compare
string2	String	Second string to compare
ignoreCase	Boolean	Optional. If TRUE, performs case-insensitive comparison. Defaults to FALSE

Return

Float value between 0.0 (completely different) and 1.0 (identical strings). Calculated as: 1.0 - (distance / max(len1, len2)).

// Calculate similarity between two strings
score = SimilarityScore("hello", "hallo");
println(score);  // prints 0.8

// Identical strings
score = SimilarityScore("test", "test");
println(score);  // prints 1.0

// Case-insensitive comparison
score = SimilarityScore("Hello", "hello", true);
println(score);  // prints 1.0
