The length of the vector.

operator*() [1/2]

double GEOM_FADE2D::Vector2::operator*

(

const Vector2 &

other

)

const

Computes the scalar product of the current vector and another vector.

Parameters

other

The other vector to compute the scalar product with.

Returns

The scalar product of the two vectors.

operator*() [2/2]

Vector2 GEOM_FADE2D::Vector2::operator*

(

double

const

Multiplies the vector by a scalar value.

Parameters

val	The scalar value to multiply by.

Returns

A new vector resulting from the multiplication.

operator/()

Vector2 GEOM_FADE2D::Vector2::operator/

(

double

val

)

const

Divides the vector by a scalar value.

Parameters

val	The scalar value to divide by.

Returns

A new vector resulting from the division.

operator=()

Vector2& GEOM_FADE2D::Vector2::operator=

(

const Vector2 &

other
