ChampCalc © is a powerful scientific calculator that supports very large numbers and extreme precision of more than 130 digits. The calculator detects and shows repeating decimal numbers (periodic numbers) on the display and interfaces, and allows to edit them inside the expression.

The calculator fully supports complex numbers in both rectangular and polar forms, as well as in Degrees-Minutes-Seconds (DMS) format. These formats can be used freely in expressions, within functions, and across various interfaces. Additionally, you have the option to select any of these formats for the displayed result.

The calculator provides a wide variety of domains such as mathematics, trigonometry, logarithms, statistics, percentage calculations, base-n operations, scientific constants, unit conversions, and more.

Additionally, the calculator includes an advanced programmer's mode that supports binary, octal, and hexadecimal number systems. It offers logical operations, bitwise shifts, rotations, and more. You can adjust the number of bits for making the calculations and also select between Signed or Unsigned number representations.

Editing calculations is made easy with a multi-line expression editor and customizable syntax highlighting, ensuring a user-friendly experience. The calculator's design focuses on ease of use, professional aesthetics, high-quality themes, and customizable syntax colors.

A built-in user manual is available to help you learn and effectively use the calculator.
