Purpose
----
These functions provides the condition number of various elementary functions.
Their goal is to evaluate the potential numerical difficulty of evaluating
numerically a function at a given point.
We may use this module while testing a given function.
The toolbox is based on macros.
To get an overview of the functions in this module, use :
help condnb_overview
This module uses the apifun module.
