`Rounded` option in the `normalize` function

[hurak]

I am checking the code for the normalize function at https://github.com/JuliaMath/Decimals.jl/blob/master/src/norm.jl and I suspect there are two problems in how the rounded option is handled.

First, the code on line 12 is run if rounded is set to true. But clearly this line computes the output without rounding. It is only the else branch that does something containing rouding. I suspect the logic here is inverted.

Second, on line 14, where rounding is performed, the digits parameter is set to DIGITS. But it is unclear to me where this DIGITS comes from - it is not entered while calling the normalize function. Is it intended to be a global variable? EDIT: I see, it is a const set in the module to 20. It does not work anyway as I would anticipate. The code below:

julia> h = Decimal(0,2540,-4)
Decimal(0, 2540, -4)

julia> f = normalize(h)
Decimal(0, 254, -3)

julia> f = normalize(h,rounded=false)
Decimal(0, 254, -3)

julia> f = normalize(h,rounded=true)
Decimal(0, 254, -3)

julia> DIGITS=1
1

julia> f = normalize(h,rounded=true)
Decimal(0, 254, -3)

For comparision with a standard float:

julia> round(0.254,digits=1)
0.3

I am running this in REPL.
