Random
new(p1 = v1)public
Creates new Mersenne Twister based pseudorandom number generator with seed. When the argument seed is omitted, the generator is initialized with Random.new_seed.
The argument seed is used to ensure repeatable sequences of random numbers between different runs of the program.
prng = Random.new(1234) [ prng.rand, prng.rand ] #=> [0.191519450378892, 0.622108771039832] [ prng.integer(10), prng.integer(1000) ] #=> [4, 664] prng = Random.new(1234) [ prng.rand, prng.rand ] #=> [0.191519450378892, 0.622108771039832]
