Constants built into distrEx.
EULERMASCHERONICONSTANT APERYCONSTANT
distrEx has a small number of built-in constants.
The following constants are available:
EULERMASCHERONICONSTANT
: the Euler Mascheroni constant
gamma=-digamma(1)
given in http://mathworld.wolfram.com/Euler-MascheroniConstant.html (48);
APERYCONSTANT
: the Apéry constant
zeta(3) = 5/2 sum_{k>=0} (-1)^(k-1)/(k^3 * choose(2k,k))
as given in http://mathworld.wolfram.com/AperysConstant.html, equation (8);
These are implemented as variables in the distrEx name space taking appropriate values.
