API Reference > geometry-core > CartesianGeometry > AngleSweep > angleToUnboundedFraction angleToUnboundedFraction Method return the fractionalized position of the angle, computed without consideration of 2PI period. That is, an angle that is numerically much beyond than the end angle will produce a large fraction and an angle much beyond the start angle will produce a large negative fraction. angleToUnboundedFraction(theta: Angle): number Parameter Type Description theta Angle Returns - number Defined in core/geometry/src/geometry3d/AngleSweep.ts Line 166 Last Updated: 13 June, 2024
