module RandomData
module Numbers
#n can be an Integer or a Range. If it is an Integer, it just returns a random
#number greater than or equal to 0 and less than n. If it is a Range, it
#returns a random number within the range
# Examples
#
# >> Random.number(5)
# => 4
# >> Random.number(5)
# => 2
# >> Random.number(5)
# => 1
def number(n)
n.is_a?(Range) ? n.to_a.rand : rand(n)
end
# return a random bit, 0 or 1.
def bit
rand(2)
end
# return an array of n random bits.
def bits(n)
x = []
n.times {x << bit}
