# Functions
Angle Returns the angle of the vector from p0 to p1, relative to the positive X-axis.
Between Returns the smallest angle between two vectors.
BetweenOriented Returns the oriented smallest angle between two vectors.
Diff Computes the smallest difference between two angles.
InteriorAngle Computes the interior angle between two segments of a ring.
IsAcute Tests whether the angle between p0-p1-p2 is acute.
IsObtuse Tests whether the angle between p0-p1-p2 is obtuse.
MatrixAngle Returns the angle of the vector from (0,0) to p, relative to the positive X-axis.
Normalize Computes the normalized value of an angle, which is the equivalent angle in the range ( -Pi, Pi ].
NormalizePositive Computes the normalized positive value of an angle, which is the equivalent angle in the range [ 0, 2*Pi ).
Quadrant Returns the quadrant of a directed line segment from p0 to p1.
QuadrantFloat Returns the quadrant of a directed line segment (specified as x and y displacements, which cannot both be 0).
ToDegrees Converts from radians to degrees.
ToRadians Converts from degrees to radians.
Turn Returns whether an angle must turn clockwise or counterclockwise to overlap another angle.
