CODATA recommended values of physical constants.

codata-recommended-values

CODATA recommended values of physical constants.

See <http://physics.nist.gov/cuu/index.html>.

All CODATA recommended values are defined as a constant and as a
function.  The function returns three values, the value of the
constant, the standard uncertainty, and the relative standard
uncertainty.  Floating-point numbers are of the type `long-float'.
Please note that some of the constants have values which can not be
represented as IEEE 754 single precision floating-point numbers.

Usage:

     (ql:quickload :codata-recommended-values)

     (defun E (m)
       (symbol-macrolet ((c codata-recommended-values:speed-of-light-in-vacuum))
         (* m c c)))

The latest values are available via the `codata-recommended-values'
package.  If you need a previously issued value, append the year to
the package name, for example, `codata-recommended-values-2010'.
