Gilles commented on GEOMETRY-50:
--------------------------------
bq. Creating double[] unnecessarily isn't performant.
Perhaps, but given the relative complexity of
[{{SafeNorm}}|https://gitbox.apache.org/repos/asf?p=commons-numbers.git;a=blob;f=commons-numbers-arrays/src/main/java/org/apache/commons/numbers/arrays/SafeNorm.java],
the assertion should be backed with
[benchmarks|https://openjdk.java.net/projects/code-tools/jmh/].
> Overflow in Vector norm and distance
> ------------------------------------

> Key: GEOMETRY-50
> URL: https://issues.apache.org/jira/browse/GEOMETRY-50
> Project: Apache Commons Geometry
> Issue Type: Bug
> Reporter: Baljit Singh
> Priority: Major
>
> 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.
