Specs

length_squared(vec2()) :: float()

length_squared(a) finds the square of the length of a vec2 (a).

In many cases, this is sufficient for comparisions and avaoids a sqrt.

It returns a float of the value (axax + ayay). length_squared(a) finds the square of the length of a vec2.

a is the vec2 to find the length squared of.

It returns a float of the value a<sub>x</sub><sup>2</sup> + a<sub>y</sub><sup>2</sup>.

In many cases, this is sufficient for comparisons and avoids a square root.
