All the fundamental constants in the updated software revision (5447) are correct to 12 significant digits (almost).

Minor quibble: f0 (the 1eV-photon frequency) is incorrectly rounded up in the constants library.

f0=c/(lambda0)=c*e/h=2.417 989 349 604 730 E14So the value, rounded to 12 significant digits, should be:

where

c = speed of light in a vacuum

e = the magnitude of electrical charge on an electron

h = Planck constant

lambda0 = 1eV-photon wavelength

f0= 241 798 934 960 000

Thank you for the software revision and updating the constants,
