[jira] [Created] (MATH-1480) Overflow in Vector norm and distance

Baljit Singh created MATH-1480:
----------------------------------

             Summary: Overflow in Vector norm and distance
                 Key: MATH-1480
                 URL: https://issues.apache.org/jira/browse/MATH-1480
             Project: Commons Math
          Issue Type: Bug
            Reporter: Baljit Singh


In Euclidean Vector classes (Vector2D, Vector3D), norm() and distance() rely on Math.sqrt(), which can overflow if the components of the vectors are large. Instead, they should rely on SafeNorm.
