| Summary | Software Carry-Save Multiple-Precision Library | |||||||||||||||||||||||||
| Description | The Software Carry-Save (SCS) Library is a fast and lightweight multiple-precision library. SCSLib has the following features: - Multiple-precision SCSLib is a fixed-precision library, where precision is selected at compile-time. Out-of-the-box, the library ensures 210 bits of precision (quad-double). - Floating-point format The SCS format is a floating-point format where exponents are machine integers (usually 32-bit numbers), which ensures a huge exponent range. - Supported operations SCSLib currently offers addition/subtraction, multiplication, and an experimental division, plus all the useful conversion functions. - IEEE-754 compatibility The range of SCS numbers includes the range of IEEE double-precision numbers, including denormals and exceptional cases. Conversions between SCS format and IEEE-754 doubles, as well as arithmetic operations, follow the IEEE rules concerning the exceptional cases. SCS doesn't ensure correct rounding, but provides conversions to doubles in the four IEEE-754 rounding modes. - Performance SCSLib is designed to be fast. With 210 bits, it outperforms MPF for most operations on most architectures. | |||||||||||||||||||||||||
