    Julia's standard library includes a host of mathematical functions, in addition to the standard operators. Complex numbers are also supported, using the built-in im unit:

    round(pi) 
    lcm(54, 392, 232) # least common multiple 
    sqrt(square(100)) 
    e^(pi * im) 
    log(e ^ 2) + log10(100)

    When you're ready, type "next" to continue
    julia> round(pi)
    no method round(MathConst{:π},)

    function foo()
      return 42
    end

    function bar()
      return foo()
    end

    function foo()
      return 69
    end
