OEGeom2DAngle
OEGeom2DAngle(p: OEFloatArray, q: OEFloatArray, r: OEFloatArray) -> float
OEGeom2DAngle(p: OEDoubleArray, q: OEDoubleArray, r: OEDoubleArray) -> float
Determines the angle in two dimensions between p, q and r.
The result is in radians. The two dimensional array q represents the
vertex for angle calculation.
