Static Methods

goog.math.Coordinate.difference(a, b) ⇒

goog.math.Coordinate

Returns the difference between two coordinates as a new goog.math.Coordinate.

Arguments:

a :

goog.math.Coordinate

A Coordinate.

b :

goog.math.Coordinate

A Coordinate.

Returns:

goog.math.Coordinate

A Coordinate representing the difference between {@code a} and {@code b}.

code »

goog.math.Coordinate.distance(a, b) ⇒

number

Returns the distance between two coordinates.

Arguments:

a :

goog.math.Coordinate

A Coordinate.

b :

goog.math.Coordinate

A Coordinate.

Returns:

number

The distance between {@code a} and {@code b}.

code »

goog.math.Coordinate.equals(a, b) ⇒

boolean

Compares coordinates for equality.

Arguments:

a :

goog.math.Coordinate

A Coordinate.

b :

goog.math.Coordinate

A Coordinate.

Returns:

boolean

True iff the coordinates are equal, or if both are null.

code »

goog.math.Coordinate.squaredDistance(a, b) ⇒

number

Returns the squared distance between two coordinates. Squared distances can be used for comparisons when the actual value is not required. Performance note: eliminating the square root is an optimization often used in lower-level languages, but the speed difference is not nearly as pronounced in JavaScript (only a few percent.)

Arguments:

a :

goog.math.Coordinate

A Coordinate.

b :

goog.math.Coordinate

A Coordinate.

Returns:

number

The squared distance between {@code a} and {@code b}.

goog.math.Coordinate.sum(a, b) ⇒
