    Javafastcomplex

    Javafastcomplex has both mutable and immutable complex numbers

    Javafastcomplex is a fast complex number package for Java. Most existing complex number packages implement only immutable complex numbers, which is easy to understand given that immutable objects lead to more understandable code. Mutable complex numbers would avoid garbage-collection penalty and therefore be faster in calculations. Javafastcomplex implements both mutable and immutable complex numbers, and has a common interface for both, allowing users to write functions that can take either...

    java-numbers

    A library for working with various complex numbers in Java.

    Java-Numbers is a library for working with complex numbers of arbitrary precision in Java. Currently I have implemented Rational, which describes rational numbers in vulgar form. For example instead of 1/3 becoming the irrational 0.3333..., it remains 1/3, and so operations on it result in what was intend, i.e. (1/3) * (3) = 1, and not 0.3333... * 3.0 = 0.9999...

    fastest primes

    A fast prime number generator based on the Sieve of Eratosthenes

    The purpose of this project is to make a prime number generator that offers many user adjustable settings and that is also very fast. While there are other prime number generators that can still beat this one in speed, no other ones that I am aware of allow the level of adjustment of sieve size that this one does. If you are running 64-bit Windows, make sure to download the 64-bit executable as it is faster than the 32-bit executable.
