static function operator -(a: Vector4, b: Vector4): Vector4;
static Vector4 operator -(Vector4 a, Vector4 b);
static def operator -(a as Vector4, b as Vector4) as Vector4
Description

Subtracts one vector from another.

Subtracts each component of b from a.
	// prints (-5.0,-3.0,-1.0,1.0)
	print (Vector4(1,2,3,4) - Vector4(6,5,4,3));

Description

Negates a vector.

Each component in the result is negated.
