%description
The IBM Accurate Portable Mathematical library (IBM APMathLib)
consists of routines that compute some of the standard common
transcendental functions. The computed results are the exact
theoretical values correctly rounded (nearest or even) to the
closest number representable by the IEEE 754 double format.
The computations are bit-by-bit compatible upon porting among
the supported platforms. Currently the supported platforms/compilers
are: x86/Linux/gcc, x86/NT/[gcc| cl], Sparc/Solaris/gcc,
PowerPC/AIX[32bit | 64bit]/[gcc | xlc].
