fdlibm
     
        A new version of the {C} maths library, libm, by Dr. K-C Ng.
        It is the basis for the bundled /usr/lib/libm.so in Solaris
        2.3 for SPARC and for future Solaris 2 releases for x86 and
        PowerPC.  It provides the standard functions necessary to pass
        the usual test suites.  This new libm can be configured to
        handle exceptions in accordance with various language
        standards or in the spirit of {IEEE 754}. The C source code
        should be portable to any IEEE 754 system.
