Number To Word - Advanced Number Converter

An advanced, high-performance web tool designed to convert extremely large numbers into Bangla words and vice versa. It supports both the modern Bangla numbering system (Hajar, Lokkho, Koti) and the ancient Sanskrit-based mathematical system.

🚀 Key Features

• Massive Number Support: Uses JavaScript BigInt to process numbers far beyond the limits of standard calculators (quadrillions, quintillions, and more).
• Three Conversion Modes:
  1. Number to Word (Modern): Converts digits into the standard Bangla naming system (লক্ষ, কোটি).
  2. Word to Number (Reverse): Parses Bangla spelling back into digits with high accuracy.
  3. Sanskrit/Ancient System: Converts numbers into rare traditional units like Arbud (অর্বুদ), Shankha (শঙ্খ), and Parardha (পরার্ধ).
• 🔊 Integrated TTS (Text-to-Speech): Real-time high-quality Bangla Voice Output.
• Reference Library: Interactive grid for numbers 1 to 99 with individual audio pronunciations.
• Mobile Responsive: Fully optimized for smartphones, tablets, and desktops using Tailwind CSS.
• Zero Dependencies: Built with vanilla HTML, CSS, and JS for lightning-fast performance.

🛠️ Tech Stack
