Global Functions

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}.

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.

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}.
code »
goog.math.Coordinate.sum(a, b) ⇒
goog.math.Coordinate
Returns the sum of 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 sum of the two coordinates.
