The F-789SGA II is a high-end scientific calculator popular in specific regions (particularly the Middle East and Asia) for students in middle and high school. It sits in a similar category to the Casio fx-991 series but offers a few distinct advantages.
Key Features:
Since a dedicated emulator isn't available, here are the best ways to achieve the functional equivalent of the F-789SGA II on your devices.
Canon provides a JavaScript-based web simulator for some of its calculators, including the F-789SGA II. This is not a downloadable emulator but a live, interactive web page.
| Goal | Best Solution | |------|----------------| | Exact Canon F-789SGA II experience on mobile | Canon Calculator App | | Desktop calculator with similar features | Qalculate! or SpeedCrunch | | Teaching with projector | Borrow physical unit + document camera | | Software development / testing | Reverse engineer (not recommended) |
Final verdict: There is no freely available, accurate, and safe desktop emulator of the Canon F-789SGA II. Use the official mobile app or a high-quality open-source scientific calculator instead.

The Canon F-789SGA II Emulator is a high-precision software version of Canon's flagship scientific calculator, designed primarily for Windows PC. It mirrors the physical Canon F-789SGA II , a calculator that gained significant traction in engineering circles for its high precision (20 internal digits) and inclusion on professional licensure "whitelist" exams. Key Features & Performance
Massive Functionality: It supports all 605 functions found on the hardware, including 4x4 matrix operations, 4-unknown equation solvers, and advanced vector calculations.
Speed Upgrades: A primary complaint of the original F-789SGA was its slow processing speed for integration and shift solving. The "II" version, and its emulator, feature significantly faster processing. canon f-789sga ii emulator
Textbook Display: The emulator uses a Dual Way Textbook Display, allowing users to input and view complex formulas in a standard handwritten style.
Built-in Tools: Includes 172 unit conversion patterns and 79 built-in constants, making it highly effective for physics and engineering students. User Experience for Professionals
Educational Utility: Canon officially offers these emulators to academic professionals to help them create classroom materials and demonstrate keypress sequences for students.
Multi-Window Support: Unlike mobile apps, the PC emulator allows for a separate LCD window that can be enlarged or captured (screenshot) for reports or teaching presentations.
Accessibility: While the physical unit is prized for its exam-ready transparent design, the emulator provides "no-waiting" access for students who may have missed out on physical stock. Canon F-789SGA II Calculator: 605 Functions & More

Registration: Users typically need to register via an official form or QR code provided by Canon regional offices (such as Canon Calculators PH) to receive the download link. Key Features of the Emulator
The emulator mirrors the physical F-789SGA II hardware, which is a major update to the original F-789SGA.
Canon F-789SGA II Emulator is a Windows PC software program provided by Canon specifically designed for educators, academic professionals, and students. It mirrors the exact layout and full suite of features found on the physical Canon F-789SGA II scientific calculator.
The core software capabilities and the mathematical features it emulates include the following: 💻 Software & Emulator Features Full Product Simulation:
Displays a high-resolution, interactive image of the real physical calculator on your computer screen. Separable & Enlargeable LCD:
Allows you to detach the LCD display into a standalone window and scale it up. This makes it highly effective for projecting calculations to a full classroom. Screen Capturing:
You can instantly copy the image of the LCD display directly to your Windows clipboard or export it as a bitmap file to drop into presentations or worksheets. Auto-Reset on Exit:
All memory banks and current operating settings are automatically wiped clean and initialized as soon as you exit the emulator. Platform Availability: Officially supported on Windows PCs. 🧮 Mathematical Capabilities Emulated Last updated: 2026 – Check Canon’s official website
Both the physical calculator and the emulator share an identical catalog of 605 advanced functions Textbook Display:
Features both 'Line' mode and 'Mathematic' mode to show inputs, fractions, and symbols exactly how they are written in textbooks. High Precision:
Boasts extremely high internal calculation accuracy (up to 18-20 digits depending on the operation). Advanced Algebra & Calculus:
Solves systems of equations with up to 4 unknowns and polynomials up to the 4th degree. It also handles integration and differentiation operations. Matrix & Vectors: Supports matrix calculations up to and vector operations up to Built-in Science Data:
Pre-loaded with 79 constant values and 172 patterns of unit conversions for rapid engineering referencing. Contextual "APPS" Key:
Features a dedicated APPS menu button that instantly pulls up context-sensitive shortcut menus based on the mathematical mode you are currently using.
Are you looking to download this emulator for teaching purposes, or are you trying to troubleshoot a specific operation on it?
Teachers often want to project the calculator screen onto a whiteboard.
Instead of an emulator, look for apps with the same function layout. The popular "Calculator V2 Plus" or "Calcu" apps allow you to download custom skins. Some third-party developers have created skins that visually mimic the Canon F-789SGA II.
