# vectorMagnitudeSqr

*Command · Math - Vectors · Arma 3 v1.22*

## Description

Squared magnitude of a 3D vector.

> [!NOTE]
> **Since Arma 3 v2.14:** Since Arma 3 v2.14 any count of numbers is valid.
>
> Before Arma 3 v2.14, the argument had to be vector 3D, or Arma 3 v2.00 2D (With z coordinate defaulted to 0)
