## Package org.apache.commons.math3.geometry.spherical.oned Description

This package provides basic geometry components on the 1-sphere.

We use here the topologists definition of the 1-sphere (see Sphere on MathWorld), i.e. the 1-sphere is the one-dimensional closed curve defined in 2D as x2+y2=1.
