Why does GCon assign units of “degrees” to curvature difference?

Results of GCon:

Command: GCon

First curve - select near end

Second curve - select near end

Curve end difference = 0.000 inches

Radius of curvature difference = 1.734 inches

**Curvature direction difference in degrees = 13.176**

Tangent difference in degrees = 13.176

Curves are G0.

Curvature has dimensions of 1/Length. Degrees are dimensionless. The units for the other metrics are appropriate.
