 * Compares a 2D vector with another vector using an epsilon value for floating-point comparison.

 * @param {ArrayVector2D} xy2 - Second vector as `[x, y]`
 * @param {number} epsilon - Maximum difference between components to consider them equal (default: `Number.EPSILON`)
 * @returns {boolean} `true` if the vectors are equal, `false` otherwise
