QuickSolve Calculation Engine 🚀

A high-precision, action-based calculation engine for Laravel, specifically designed for POS and Financial Systems. Built with SOLID principles and BCMath for "Bank-level" mathematical accuracy.

✨ Features

• ✅ Action Pattern: Clean, modular logic for Taxes and Discounts.
• 🔢 BCMath Integration: Eliminates floating-point precision errors.
• 🔗 Fluent Interface: Beautiful and readable method chaining.
• 🧪 Unit Tested: Ensuring 100% reliability in financial calculations.
• 🚀 Laravel Ready: Includes Facades for seamless integration.

📦 Installation

You can install the package via composer:

composer require quicksolve/laravel-calc

Note: Ensure the bcmath PHP extension is enabled on your server.

🚀 Usage

Using the engine is simple and intuitive. You can use the QuickSolve Facade:

use QuickSolve\Calc\Facades\QuickSolve;

// Basic calculation
$total = QuickSolve::setAmount(1000)
            ->addTax(15)        // Adds 15% Tax
            ->applyFlatDiscount(50) // Deducts flat 50
            ->get();            // Returns 1100.00

// Formatting for display
echo QuickSolve::setAmount(1250.50)->format('LKR'); 
// Output: LKR 1,250.50

🛠 Planned Features (Roadmap)

• Multiple Tax Support: Ability to stack multiple tax types (VAT, SSCL, etc.).
• Service Charges: Built-in action for hospitality service fees.
• Rounding Strategies: Support for various rounding modes (Half Up, Half Down, etc.).
