Description:
|
The system tolerances are returned in the following order:
SPAresabs,
SPAresnor,
SPAresfit, and
SPAresmch.
|
|
|
SPAresabs
|
determines if two positions in space are equal. This tolerance defines the smallest distance between two distinct points.
|
|
SPAresnor
|
checks a number for equality with 0. This checks components of numbers that are 0 for determining if vectors are parallel or perpendicular, or for checking for zero lengths.
|
|
SPAresfit
|
fits interpolation curves when intersecting surfaces.
|
|
SPAresmch
|
is used by the spline package for purposes similar to the use of
SPAresnor in the system.
