length_squared(a)
Specs
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.
