Random#seed

prng.seed → integer

static VALUE
random_get_seed(VALUE obj)
{
    return get_rnd(obj)->seed;
}

Returns the seed value used to initialize the generator. This may be used to initialize another generator with the same state at a later time, causing it to produce the same sequence of numbers.

Example

prng1 = Random.new(1234)
prng1.seed       #=> 1234
prng1.rand(100)  #=> 47

prng2 = Random.new(prng1.seed)
prng2.rand(100)  #=> 47
