Pointers

The s21_decimal project involves implementing a custom C library for high-precision decimal arithmetic, targeting financial calculations where floating-point errors are unacceptable. The library provides a 128-bit decimal type using a structure of four 32-bit integers, supporting numbers from approximately ±7.9e28 with up to 28 decimal places. Key features include arithmetic operations (add, subtract, multiply, divide), comparisons, conversions to/from int/float, and rounding functions (floor, round, truncate, negate), all designed to minimize rounding errors through bank rounding and precise binary representation. The implementation adheres to structured programming principles, includes comprehensive unit tests, and is delivered as a static library.
