| 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.
