What is DeciMojo? (short intro)
DeciMojo provides high-precision numeric types for Mojo:
• BInt — a drop-in replacement for Python int in Mojo (arbitrary-precision integers)
• BigDec — a drop-in replacement for Python Decimal in Mojo (arbitrary-precision decimal arithmetic)
On top of that, it could be a foundation for projects like a finance/tax or invoice calculator, a scientific calculator, stable JSON serialization for exact numeric output, or even basic symbolic computation.
Feedback is welcome!
