      Description

      References:

      Notable difference:

      • With similarity, the Oracle version returns a normalized result ranging from 0 to 100.
      • In the Appache version, null values result in exceptions.
      • Apache rounds the values to two digitsĀ 

      The scaling factor of the algorithm can be added as an extra/default argument.
