C++ BigInt class that enables the user to work with arbitrary precision integers. Latest Version: 10.3 (2019-03-06)

A tool written in C++ to generate very large Fibonacci numbers using the primary recursive formula: F(n) = F(n-1) + F(n-2) n > 1; F(1) = 1, F(0) = 0.

A program designed to imitate the graphing capabilities of the Ti-XX series of calculators. While improving accuracy.

Wolfgang is a lightweight tool that allows users to easily create and edit Petri nets and check them against general and workflow specific net properties. Specifically, Wolfgang supports full PNML conform editing functionality of Place-Transition Nets (P/T-Nets) and Colored Petri Nets (CPN) as they are defined in the SEPIA package. Its simple and easy to use interface allows to quickly create Petri nets from scratch, edit them graphically in many ways, store and even export them as PDFs. Use Wolfgang to smoothly create the Petri net you want! A user guide and a documentation can be found under http://doku.telematik.uni-freiburg.de/wolfgang.

A command line calculator capable of complex arithmetics.

The project takes an input 1-dimensional sequence and attempts to find a formula for the sequence.

This package provides high-level interface utilities for MCMC models via Just Another Gibbs Sampler (JAGS), facilitating the use of parallel (or distributed) processors for multiple chains, automated control of convergence and sample length diagnostics, and evaluation of the performance of a model using drop-k validation or against simulated data. Template model specifications can be generated using a standard lme4-style formula interface to assist users less familiar with the BUGS syntax. A JAGS extension module provides additional distributions including the Pareto family of distributions, the DuMouchel prior and the half-Cauchy prior.

Tinger Calc is a powerful scientific calculator environment. It supports elementary math ( +, -, *, /, ^), trigonometric functions (sin, sinh, asin, cos, cosh, acos, tan, tanh, atan), exponential functions (exp, ln, lg, sqrt), math constants (pi, e), system functions (exit, quit, print).
