[julia-users] Re: Master list of constants

[Lyndon White]

You can use the `names` function to search a module for all constants it 
defines.
By evaluating the names to get the values, then checking if they are 
Irrational (formerly known as MathConst?)
By doing this, I conclude that the  ASCII name for the Euler-Mascheroni 
constant (γ) is eulergamma


 


julia> for name_sym in names(Base)
              value = eval(name_sym)
              if typeof(value)<: Irrational
                            println(name_sym, "\t", value)
              end
       end
