KCalc26.04.3

Enter numbers and mathematical operations in KCalc to produce numerical results for desktop work. Its scientific-calculator feature set includes trigonometric functions, logic operations, and statistical calculations. It suits users who need a desktop calculation tool for checking figures, working through multi-step numerical problems, or retaining results for later use.

Earlier answers remain in a results stack, allowing a previous value to be recalled instead of entered again. A precision setting determines how much numerical detail appears for each calculation. Values in the display can be cut and pasted with its standard text-editing actions, making it practical to transfer results into other text-based work. The display’s colors and font are configurable, so its presentation can be adjusted to different preferences. Key-bindings provide keyboard control without a pointing device, which is useful during keyboard-centered calculation sessions.

KDE develops and publishes KCalc under an open-source license. The current version is 26.04.3, and it requires Linux with snapd on x86_64 (amd64) architecture.
