Hello, In the symbolic environment CAS, the following mathematical expression should return euler_gamma constant


limit(Σ(1/k,k,1,n)-ln(n),n, +infinity) [enter] 0.577215664902 // current hp-prime
limit(Σ(1/k,k,1,n)-ln(n),n, +infinity) [↵] returns euler_gamma // Xcas


for which it is required to add the constant euler_gamma in a future version

euler_gamma [↵] Xcas returns euler_gamma
evalf(euler_gamma) [↵] Xcas returns 0.577215664902
%gamma -> 0.577215664902 // MAXIMA CAS
