Portable Kalkules

Portable Kalkules is a lightweight cross-platform utility that comes packed with a scientific calculator for helping users perform various mathematical operations.
Since this is the portable version of the program, it is important to mention that it doesn’t leave any traces in the Windows Registry. You can copy it on any USB flash drive or other devices, and take it with you whenever you need to make some math calculations on the breeze.
Apart from performing basic operations, such as addition, subtraction, multiplication and division, as well as using trigonometric functions like sine, cosine, tangent and others, it is possible to work with different polynomial expressions, combinatorics, statistics, derivatives, and quadratic equations.
The program allows users to select the angle unit (degrees, radians or gradians) and numeral system (hexadecimal, decimal, octal or binary), choose from different constants and geometrical formulas (e.g. circle, triangle, rectangle, tapezoid), view prefix values, as well as add your own expressions and draw graphs based on functions.
What’s more, Portable Kalkules gives users the possibility to perform different unit measurement conversions, namely angle, area, energy, mass, power, pressure, time, speed, volume, temperature, and others.
You can copy the results to the Clipboard and make the program remain on top of other applications. What’s more, it keeps a history with all the performed operations which can be saved to a plain text file.
To sum things up, Portable Kalkules comes packed with many useful features and a clean layout for helping you when it comes to performing various mathematical operations.
