This package provides often needed constants from mathematics,
machine dependent constants and constants from nature. The latter
constants (name, value, description) are from the following source
(based on the second source):
- Michael Stock, Richard Davis, Estefanía de Mirandés and Martin
J T Milton:
- The revision of the SI-the result of three decades of
progress in metrology in Metrologia, Volume 56, Number 2.
