-Returns a [Linear congruential generator](https://en.wikipedia.org/wiki/Linear_congruential_generator). The generator can be called repeatedly to obtain a pseudo-random sequence of values, well-distributed on the interval [0,1) and with a long period (up to 1 billion numbers).

-A *seed* can be specified as a number in the interval [0,1). Two generators instanced with the same seed generate the same sequence, allowing to create reproducible pseudo-random experiments. If the *seed* is not specified, it is chosen at random.
+Returns a [linear congruential generator](https://en.wikipedia.org/wiki/Linear_congruential_generator); this function can be called repeatedly to obtain pseudorandom values well-distributed on the interval [0,1) and with a long period (up to 1 billion numbers), similar to Math.random. A *seed* can be specified as a number in the interval [0,1). Two generators instanced with the same seed generate the same sequence, allowing to create reproducible pseudo-random experiments. If the *seed* is not specified, one is chosen using Math.random.
