Range for core function rand()


#1

I couldn’t find it in docs. If
X=rand(), then
X comes from [0 1] or [0 1) or some other variance?

  rand([rng=GLOBAL_RNG], [S], [dims...])

  Pick a random element or array of random elements from the set of values specified by S; S can be

    •    an indexable collection (for example 1:n or ['x','y','z']), or

    •    a type: the set of values to pick from is then equivalent to typemin(S):typemax(S) for integers (this is not applicable to BigInt), and to [0, 1) for floating point numbers;


  S defaults to Float64.

Note: “to [0, 1) for floating point numbers”
