class LinearCongruentialGenerator:
    A pseudorandom number generator.

    # The default value for **seed** is the result of a function call which is not
    # normally recommended and causes flake8-bugbear to raise a B008 error. However,
    # in this case, it is accptable because `LinearCongruentialGenerator.__init__()`
    # will only be called once per instance and it ensures that each instance will
    # generate a unique sequence of numbers.

    def __init__(self, multiplier, increment, modulo, seed=int(time())):  # noqa: B008
        These parameters are saved and used when nextNumber() is called.

        modulo is the largest number that can be generated (exclusive). The most
        efficient values are powers of 2. 2^32 is a common value.
        self.multiplier = multiplier

    def next_number(self):
        The smallest number that can be generated is zero.
        The largest number that can be generated is modulo-1. modulo is set in the
        self.seed = (self.multiplier * self.seed + self.increment) % self.modulo
