# Chapter 1. Introduction

This is release 0.4 of KCalc. KCalc is a simple but hopefully useful scientific calculator for the KDE project.

KCalc offers many more mathematical functions than meet the eye on a first glance. Please study the section on keyboard accelerators and modes in this handbook to learn more about the many functions available.

In addition to the usual functionality offered by most scientific calculators, KCalc offers a number of features, which I think are worthwhile pointing out:

- KCalc has a trigonometric and a statistics mode.

- KCalc allows you to cut and paste numbers from/into its display.

- KCalc features a 'results-stack' which let's you conveniently recall previous results.

- You can configure KCalc's display colors and font.

- You can configure KCalc's precision and the number of digits after the period.

- KCalc offers a great number of useful key-bindings, which make using KCalc without using a pointing device easy.

Have fun with KCalc!
