C++23 arbitrary-precision numeric types (BigInteger/BigDecimal/BigFloat/BigRational/BigModular/BigMatrix) built on GMP.

Small C++23 math library with custom uint128/int128, uint256/int256 and a fixed-point Numeric128<P,S>, Numeric256<P,S> type plus a big decimal Numeric, focused on predictable parsing/formatting and no external dependencies.

🔢 Simplify number handling in C++ with unumber, a lightweight library for accurate and efficient arithmetic operations.
