CoStLy is a free alternative to any expensive commercial library of complex interval standard functions. It is distributed under the terms of the GNU general public license.
M. Neher: Complex standard functions and their
implementation in the CoStLy library.
Compatibility update for gcc 4.2.1 and C-XSC 2.2.3.
Since filib++ has undergone major revision, CoStLy now only works with C-XSC.
Improved argument reduction in real sin, cos and tan.
Improved treatment of overflow exceptions in tan, cot, tanh and coth.
Improved treatment of cancellation exceptions in Asin and Acos.
New implementation of the whole library. |
|| CoStLy 1.0.0:
New implementation of the whole library.
All of the "usual" standard functions with (almost) optimal accuracy (except for over/ underflow/cancellation exceptions).
New power functions with (almost) optimal accuracy (except for over/underflow/ cancellation exceptions).
New root functions with (almost) optimal accuracy (except for over/underflow/ cancellation exceptions).
|| CoStLy 0.2:
First filib++ based version. Minor bug fixes.
|| CoStLy 0.1:
|| First release. Based on C-XSC.
There's a README file for the installation. CoStLy has been implemented and tested on PCs with Linux. The current version of the library requires the GNU C++ compiler gcc 4.2.1 (or higher; earlier versions from 2.95.2 may also work) and the C-XSC interval library (Release 2.2.3 or higher). C-XSC is available at http://www.xsc.de.
