BarnesDoubleGamma.jl documentation
This is the documentation page for the BarnesDoubleGamma package. BarnesDoubleGamma is a julia package for computing Barnes' double gamma functions, see this wikipedia article for a reference. The package works with real and complex numbers, in standard and multiple precision:
julia> β = 0.74; w = 1.42; v1 = doublegamma(w, β)
1.3302721668409918
julia> w = big(w); v2 = doublegamma(w, β)
