Interface RandomExponential

A configurable random number generator for the exponential distribution.

interface RandomExponential {
    source(source): RandomExponential;
    (lambda): (() => number);
}

Hierarchy

  • Returns a function for generating random numbers with an exponential distribution with the rate lambda; equivalent to time between events in a Poisson process with a mean of 1 / lambda.

    Parameters

    • lambda: number

      Expected time between events.

    Returns (() => number)

      • (): number

        Returns number

Methods

Methods

  • Returns the same type of function for generating random numbers but where the given random number generator source is used as the source of randomness instead of Math.random. This is useful when a seeded random number generator is preferable to Math.random.

    Parameters

    • source: (() => number)

      Source (pseudo-)random number generator implementing the Math.random interface. The given random number generator must implement the same interface as Math.random and only return values in the range [0, 1).

        • (): number
        • Returns number
