This suite of C language elementary functions offers support fornot-a-number (NaN) and infinity rules, subnormal numbers, and minuszero as described by IEEE standard 754 and the Numerical C ExtensionsGroup (NCEG). For a variety of reasons, many computers cannot takeadvantage of these features. You can disable any or all of them byremoving the corresponding preprocessor macros. Check the filesmconf.h and const.c carefully to be sure they are appropriate for yoursystem.------------------------------------------http://www.netlib.org/cephes/readme Some software in this archive may be from the book _Methods andPrograms for Mathematical Functions_ (Prentice-Hall or Simon & SchusterInternational, 1989) or from the Cephes Mathematical Library, acommercial product.
