angle - Function

Geometrical function


Description

Returns the angle between the positive X-axis and a line from X=Y=0 to a given position.

Syntax

angle(x, y)

FLOAT	x;
FLOAT	y;

Principal parameters

x	- X-coordinate of position
y	- Y-coordinate of position

Optional parameters

None.

Return value

A FLOAT value equal to the corresponding angle in degrees.

Example

angle(1,0) = 0 Degrees
angle(1,1) = 45 Degrees
angle(0,1) = 90 Degrees
angle(1,-1) = -45 Degrees
angle(-1,1) = 135 Degrees

Comments

Basically does the same job as the trigonometric function angle but deals with angles larger than or equal to 90 degrees.
