What is decNumber++?
decNumber++ is a high-performance decimal arithmetic library in ISO C++ that is especially suitable for commercial and human-oriented applications. The library is a reference implementation of interfaces specified in a forthcoming ISO Technical Report on decimal arithmetic types in C++: "ISO/IEC TR 24733: C++ Decimal Floating-Point Arithmetic Extensions." In addition, the library conforms to the "Draft Standard for Floating-Point Arithmetic IEEE-P754."
This technology permits the use of decimal floating-point types in C++. Decimal floating-point arithmetic allows performance-critical business applications to conduct monetary calculations accurately and swiftly.
How does it work? decNumber++ is based on decNumber technology. The decNumber++ library supports the following:
- 32-, 64-, and 128-bit decimal floating-point formats
- conversions to and from all C++ arithmetic types
- arithmetic operators for the decimal types
- C++ TR1 floating-point environment, including rounding modes and floating-point exceptions
- input and output of decimal values using IOStreams.
