The module is an object orientated interface to allow a number and an uncertainty on the number to be stored in one tidy little bundle that can be passed around
While other, packages a lot like this one are floating around, none do exactly what required. It was easier to hack out another one than try and kludge our ideas into the form factor of an existing package.
The package provides the following classes
Number::Uncertainty
further information can be found in the POD included in Uncertainty.pm
The package is availabe from CPAN <http://www.cpan.org/>.
Installation is automated using the ExtUtils::MakeMaker library
% perl Makefile.PL
% make
% make test
% make install
The module was written by Alasdair Allan <aa@astro.ex.ac.uk>, of the University of Exeter Astrophysics Group (http://www.astro.ex.ac.uk/) as part of his work for the eSTAR project.
