RNG 0.1.17

Random Number Generator: API for the C++ Random library as a c-extension for Python3

RNG: Random Number Generator

Default Random Engine: Mersenne Twister 64, with hardware entropy. Additional engines and seeding strategies are planned to be available in the unbounded future. More info about MT64: https://en.wikipedia.org/wiki/Mersenne_Twister

The RNG module is not suitable for cryptography, and perfect for other non-deterministic needs like data science, experimental programming, A.I. and games.

Recommended Installation: $ pip install RNG

RNG is not intended to be a drop-in replacement for the Python random module.

Number Types & Sizes:

• Float: Python float -> double at the C++ layer.
• Integer: Python int -> long long at the C++ layer.
  • Input & Output Range: (-2**63, 2**63) or approximately +/- 9.2 billion billion.

  • @return :: True or False

Random Integer Functions

• random_int(left_limit: int, right_limit: int) -> int
  • Flat uniform distribution, distributed according to the discrete probability function.
  • Parameter order does not matter, that is to say, it is no longer required that lo <= hi, it just works.

Random Floating Point Functions

• generate_canonical() -> float
  • Evenly distributes real values of maximum precision.
  • @return :: random Float in range {0.0, 1.0} biclusive. The spec defines the output range to be [0.0, 1.0).
    • biclusive: feature/bug rendering the exclusivity of this function a bit more mysterious than desired. This is a known compiler bug.
• random_float(left_limit: float, right_limit: float) -> float
  • Suffers from the same biclusive feature/bug noted for generate_canonical().
  • @param left_limit :: input A
  • @param right_limit :: input B

  • @param std_dev :: standard deviation. Specifies spread of data from the mean.
• random_log_normal(log_mean: float, log_deviation: float) -> float
  • @param log_mean :: sets the log of the mean of the function.
  • @param log_deviation :: log of the standard deviation. Specifies spread of data from the mean.
• random_exponential(lambda_rate: float) -> float
  • Produces random non-negative floating-point values, distributed according to probability density function.
  • @param lambda_rate :: λ constant rate of a random event per unit of time/distance.
  • @return :: The time/distance until the next random event. For example, this distribution describes the time between the clicks of a Geiger counter or the distance between point mutations in a DNA strand.

• random_weibull(shape: float, scale: float) -> float
  • Generalization of the exponential distribution.
  • Similar to the gamma distribution but uses a closed form distribution function.
  • Popular in reliability and survival analysis.
• random_extreme_value(location: float, scale: float) -> float
  • Based on Extreme Value Theory.
  • Used for statistical models of the magnitude of earthquakes and volcanoes.
• random_chi_squared(degrees_of_freedom: float) -> float
  • Used with the Chi Squared Test and Null Hypotheses to test if sample data fits an expected distribution.
• random_cauchy(location: float, scale: float) -> float
  • @param location :: It specifies the location of the peak. The default value is 0.0.
