List of Methods

class Point

This class implements a point in the plane with euclidean metrics. It also includes several vector functions.

variables

• x: the x-coordinate of the point. private.
• y: the y-coordinate of the point. private.

equals(aVertex)

• returns true if this vertex and aVertex have the same coordinates.

dist(aVertex)

• returns the euclidean distance between this vertex and aVertex.

plus(p)

• returns the sum of this vector and p.

minus(p)

• returns the sum of this vector and -p.

times(c)

• returns this vector scaled by factor c.

dividedBy(c)

• returns this vector scaled by factor 1/c. c may not be 0.

round(numOfDigits)

• sets the precision to 10^-numOfDigits.

toString()

• If p is a point, alert(p) displays its coordinates.

all other functions are private and shall not be used.
