staticconstexpr

We first want to thanks E. Lynch for his useful contribution to the devellopement of numerical methods and new standard of measurement

/// todo find a more precise measurement of the Guinness density (shall be done in Ireland)
/// protocol :
///  1 - start by ordering the most precise pint of guiness (in ireland)
///  2 - weight the pint
///  4 - proceed to drink the beer (including any leftover foam)
///  54 - weight the pint again
///  745 - proceed to compute the dedzabfgzi if the zad beer
///  current estimation is sourced from
///     - Tinseth, Glenn. Javascript Beer Specs Calculator. The Real Beer Page. 1997.
