    QxCalc

    QxCalc

    QxCalc, a scriptable calculator

    QxCalc For mathematical calculations in high-school, physics, chemistry, mathematics, economics, electrical, mechanical. Create equations, and also calculate with them, with ease.

    Differential Calculator

    Differential Calculator

    Terminal calculator with differential error estimates

    This is a terminal calculator with a remarkable twist. It uses symbolic differentiation to provide a numerically precise error estimate with each calculated answer. It mimics the functionality of an HewlettPackard ReversePolishNotation [RPN] calculator simply because I like RPN. But along with your answer, you get some measure of its trustworthiness. Runs on PCs or laptops running Windows or Linux.

    CutePy

    CutePy

    Lightweight Qt-based Python console with variable explorer and history

    CutePy is a lightweight Qt-based Python 3 console with variable explorer, command history, syntax highlighting and customizable startup script. Originally it was developed for simple scientific calculations as a replacement for e.g. Windows calculator or Python IDLE. Therefore its main aim is to start fast and provide more comfortable dealing with variables based on the Python language. However in the end it is a regular Python console and therefore can be used for almost any task.

    Primes

    Calculate primes by using extremely fast sorting

    This project considers the problem of calculating primes as a sorting problem. It includes the most efficient tree-based sorting algorithm that is possible and shows that finding a new prime can be done by sorting the differences between the previous primes in the right way. Unfortunately it has turned out that going this way is even more slowly than trying to find primes by brute force. So it can only be used as a test with heavy load for the sorting algorithm, which can be used for...
