llRotBetween, some alternatives and considerations

Under construction

Scope

Four scripts are covered, They are

1. llRotBetween( vector a, vector b); // The built in function
2. RotBetween( vector a, vector b); // The replacement outlined in the wiki
3. rotV2V( vector a, vector b); // The shortest replacement
4. rotbetween( vector a, vector b); // Using a Vector to rotation function

Tests

First the rotation solutions were compared and they didn't compare at all. Testing rotations is a bad idea since there is no single solution, but an infinite number of solutions. All 4 functions provide different valid solutions.
