When max is a Float, rand returns a random floating point number between 0. 0 and max, including 0. 0 and excluding max. prng. rand (1. 5)# 1. . When max is a Range, rand returns a random number where true.I am trying to create a randomly generated array of x numbers with no duplicates. I am choosing numbers, one at a time, then comparing each new number to the numbers already in random number ruby

Ruby comes with a random number generator. The method to get a randomly chosen number is rand. If you call rand, you'll get a float greater than or equal to 0. 0 and less than 1. 0.
