cppdecfloat

cppdecfloat is a C++ library designed for arbitrary-precision decimal floating-point arithmetic. It allows calculations with numbers that exceed the precision of standard C++ data types like float or double. The library is implemented entirely in C++ and aims to provide a robust and efficient solution for applications requiring high precision decimal arithmetic.

The primary purpose of cppdecfloat is to handle decimal numbers with a user-defined number of digits, both before and after the decimal point. This is crucial in domains such as finance, accounting, and scientific computing where exact decimal representation and precision are paramount to avoid rounding errors inherent in binary floating-point formats.

cppdecfloat supports various arithmetic operations including addition, subtraction, multiplication, division, and exponentiation. It also provides functions for rounding, formatting, and conversions to and from standard C++ numeric types. The library emphasizes ease of use, with an interface that resembles standard C++ arithmetic operators.

Key features of cppdecfloat include its extensibility, allowing users to customize precision and other behavior. It is designed to be cross-platform, working on various operating systems and compilers that support modern C++ standards. The library aims to be a valuable tool for developers who need reliable and precise decimal calculations within their C++ applications.
