About this app

Champ Calc Pro© is a powerful scientific calculator that supports very large numbers and extreme precision of more than 130 digits.

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.

The calculator detects and shows repeating decimal numbers (periodic numbers) on the display and interfaces, allowing editing them inside the expression.

The calculator fully supports complex numbers in both rectangular and polar forms and 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.

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.

Ratings and reviews

One of only a few scientific calculators I could find that do not require extra permissions (ChampCalc, RealCalc, CalcTastic), and the only one being actively updated. I bought the Pro version to support it. A large font theme would be helpful in difficult light; the Shift labels in particular are a bit small. RealCalc is easier to use in this circumstance.

Has everything I need. Attractive and intelligent layout. Easily configurable.

Memory input, store and return function needs to be easier to understand and fluidic to use, I do have tremendous trouble accessing those and hence shifted to the real-life hardware. Earlier :- Support this project and kudos to the developer/s for this excellent as well as feature rich tool
