Built around a practical **RPN (Reverse Polish Notation)** workflow, SPEC provides a fast and organized way to perform calculations while keeping the interface focused on **precision, productivity, and ease of use**. **Scientific and Engineering Functions** SPEC includes a comprehensive collection of mathematical and scientific operations, including: * Basic arithmetic operations * Trigonometric functions: **sin, cos, and tan** * Inverse and reciprocal calculations * Square roots and powers * Natural logarithms and logarithms * Exponential functions * Absolute value * Factorial * Mathematical constants such as **π and e** * Modulo operations * Sign change * Engineering and scientific notation The calculator also supports **degree and radian modes**, allowing users to work naturally with different types of trigonometric calculations. **RPN Workflow** The RPN interface is designed for users who value efficient calculation workflows. Instead of requiring traditional algebraic expressions, calculations can be built directly using the calculator stack. SPEC provides essential stack operations such as: * **ENTER** * **SWAP** * **ROLL** * **DROP** * **LASTX** * Stack-based memory operations * Clear and reset functions This approach is particularly useful for engineering and technical calculations where intermediate values need to be preserved, manipulated, and reused. **Memory and Calculation Management** SPEC includes memory functionality for storing and recalling important values during calculations. The calculator also provides access to previous calculation information, making it easier to reuse results and maintain a continuous workflow. The interface is designed to keep the **current stack, stored values, and calculator state** clearly visible while calculations are being performed. **Designed for Precision Engineering** SPEC was created with a focus on **precision engineering**, providing a practical tool for calculations used across technical disciplines such as: * Mechanical engineering * Electrical engineering * Physics * Mathematics * Computer science * Scientific research * Other STEM fields Whether you are calculating a simple value, evaluating mathematical operations, working with trigonometric functions, or performing engineering calculations, SPEC provides a consistent and efficient environment. **Simple, Focused Interface** The interface combines a **classic scientific-calculator layout** with a modern desktop design. High-contrast controls, dedicated function keys, a clear calculation display, and organized scientific operations make the application easy to navigate while keeping advanced functionality accessible. SPEC is designed to stay focused on one task: **helping you calculate accurately and efficiently.** **Calculate. Design. Build.** **SPEC Calculator** brings scientific and engineering calculations into a single practical desktop application — built for **learning, experimentation, technical work, and everyday engineering use**. ### Package name * spec-calculator --- ### License * Proprietary --- ### Last updated * 20 October 2026 - latest/stable * 20 October 2026 - latest/edge --- ### Websites * [www.uflaniano.com.br](https://www.uflaniano.com.br/ "https://www.uflaniano.com.br/") --- ##### Report a Snap Store violation * [Report this Snap](https://snapcraft.io/install/spec-calculator/ubuntu#report-snap-modal) --- ## Enable snaps on Ubuntu and install SpecCalculator Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully. Snaps are discoverable and installable from the [Snap Store](https://snapcraft.io/store), an app store with an audience of millions. ### Enable snapd If you’re running [Ubuntu 16.04 LTS (Xenial Xerus)](https://www.ubuntu.com/) or later, including [Ubuntu 18.04 LTS (Bionic Beaver)](https://www.ubuntu.com/desktop/features) and [Ubuntu 20.04 LTS (Focal Fossa)](https://wiki.ubuntu.com/FocalFossa/ReleaseNotes), you don’t need to do anything. Snap is already installed and ready to go. For versions of Ubuntu between [14.04 LTS (Trusty Tahr)](https://wiki.ubuntu.com/TrustyTahr/ReleaseNotes) and [15.10 (Wily Werewolf)](https://wiki.ubuntu.com/WilyWerewolf/ReleaseNotes), as well as Ubuntu flavours that don’t include *snap* by default, *snap* can be installed from the Ubuntu Software Centre by searching for *snapd*. Alternatively, snapd can be installed from the command line: ``` sudo apt update sudo apt install snapd ``` Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly. ### Install SpecCalculator To install SpecCalculator, simply use the following command: ``` sudo snap install spec-calculator ``` ### Other popular snaps… [See more...](https://snapcraft.io/search?categories=featured) [See more in Featured](https://snapcraft.io/search?categories=featured) ### More things to do… #### [Get the snap store](https://snapcraft.io/snap-store) Browse and find snaps from the convenience of your desktop using the snap store snap. #### [Learn more about snaps](https://snapcraft.io/docs) Interested to find out more about snaps?
