Gets Rhino's Zero Tolerance constant, which is 2^-32. In cases when an
absolute "zero" tolerance is required to compare model space coordinates,
ZeroTolerance is used. The value of ZeroTolerance should be no smaller than
and should be several orders of magnitude smaller than SqrtEpsilon
RhinoCommon (in RhinoCommon.dll)
public const double ZeroTolerance = 2.3283064365387E-10
Public Const ZeroTolerance As Double = 2.3283064365387E-10
This is equivalent to openNURBS ON_ZERO_TOLERANCE.
