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.
