Generating random numbers in Julia

Question

How to generate a real random number in range [-1, 1] in Julia?

Sorry, I'm just starting working in Julia and I couldn't find a right answer. For example I tried

rand(Float16, [-1,1], 1)

but I get ERROR: MethodError every time.

Answer 1

Generating e.g. 10 random numbers between -1 and 1, using broadcasting

julia> rand(10) .* rand((-1,1), 10)
