Calc: Máy tính & Tiền tệ

Calc: This calculator is a high-standard digital computing tool designed to maximize efficiency for students, engineers, researchers, and financial professionals. Combining precise expression processing algorithms with a minimalist, ergonomic design philosophy, the application simplifies workflows from everyday calculations to complex technical analyses.

🎯 SUPERIOR ACCURACY AND PERFORMANCE
The application integrates the standard mXparser advanced mathematical multiplier, handling complex nested expressions and completely eliminating floating-point errors in binary mathematics. All displayed results are formatted to a maximum of 10 decimal places, ensuring the highest accuracy in engineering practice.

🛠️ SPECIAL FEATURES:
1. Comprehensive Scientific & Engineering Abacus

Calculus & Trigonometry: Full support for standard trigonometric functions (sin, cos, tan), inverse trigonometry (asin, acos, atan), and advanced hyperbolic systems (sinh, cosh, tanh) for physics and mechanics research.
Functions & Logarithms: Quick analysis of exponential functions ($x^y$), nth roots (ʸ√x), factorial ($x!$), natural logarithms ($ln$), decimal logarithms ($log_{10}$), and base-2 logarithms ($log_2$).
Modifier Key Synchronization: Dedicated 2nd key allows quick switching between advanced function sets on the same display area, saving workspace.
Unit Configuration Freedom: Quickly switch between Degrees (DEG) and Radians (RAD) to synchronize with all engineering exercises. 2. Financial Management & Foreign Exchange Rate Conversion Tools

Instant two-way foreign exchange conversion with an integrated database of over 30 of the world's most popular currencies (USD, EUR, VND, JPY, GBP, CNY...).
Exchange rate data is retrieved from reputable financial API sources and continuously updated in real time.
Intelligent caching mechanism (Offline Cache) allows financial conversions to be performed even when the device is disconnected from the network, extremely useful when traveling or on business trips.

3. Memory Management & Calculation History Monitoring

Advanced memory register: Integrates standard memory function keys (MC, MR, M+, M-) for multi-step cumulative calculations.

Workspace Auditing: Historical log stores all correct expressions and their corresponding results in reverse chronological order. Users can easily reuse old expressions with just one touch.

Local security: The entire calculation history is securely stored in the device's internal database and can be completely erased at the user's request.

4. Premium UX (Ultra-High User Experience)

Intuitive flat interface design, ergonomically optimized key spacing minimizes typing errors.
Automatic Light/Dark mode synchronization based on system mode reduces eye strain during long work sessions.
Realistic haptic feedback and soft typing sounds create a realistic physical interaction feel.
Ultra-compact size, does not run in the background, saving RAM and battery power.
