%N Decimal expansion of the electron volt-hertz relationship according to the 2019 SI system in units Hz.
%C Since the amount of energy in terms of charge and potential difference is given by E = QV, from A081823 we have that 1 eV = 1.602176634 * 10^(-19) J.
%C Now (see A003676), f = E/h and it follows that f = 1 eV/(6.62607015 * 10^(-34) J/s) = 2.417989242084918... * 10^14 s^(-1).
%F eV/h = 160217663400000/6.62607015 = 10681177560000000000000/44173801 = 241798924208491 + 36055709/44173801 s^(-1).
%e 241798924208491.81622382914252726... (rational number, period 6310542).
