Ruby array arranged in ascending order

Hi I'm making a simple function to generate a float array in ascending order but i want to know if there is a simpler way to do this.

So far this is my code

#initialice the array
x0 = []

#insert the values 5 times
5.times do
    #random float generator
    value=rand(0.1..50.1)
    x0<<value 
end

#values arranged in ascending order
x0.sort!

#printing the array
puts "lista x0" +x0.to_s
