void vect2_add_cart	(	vect2_cart *	v1,
		vect2_cart *	v2,
		vect2_cart *	vresult
	)

Add 2 cartesian vectors and return the result.

Parameters:

	v1	Reference to a cartesian vector to sum.
	v2	Reference to a cartesian vector to sum.
	vresult	Reference to a polar vector to store the result.

Warning:: This function doesn't do any malloc ! You have to allocate structures before calling this function.

void vect2_add_pol	(	vect2_pol *	v1,
		vect2_pol *	v2,
		vect2_pol *	vresult
	)

Add 2 polar vectors and return the result.

Parameters:

	v1	Reference to a polar vector to sum.
	v2	Reference to a polar vector to sum.
