libintelrdfpmath-dev binary package in Ubuntu Noble ppc64el

 Software implementation of the IEEE 754-2008 Decimal Floating-Point
 Arithmetic specification, aimed at financial applications, especially
 in cases where legal requirements make it necessary to use decimal, and
 not binary floating-point arithmetic (as computation performed with
 binary floating-point operations may introduce small, but unacceptable
 errors).
 .
 This library is only fully supported on amd64, i386, and ia64. It
 builds on several other Debian architectures, but you should check
 the test results to determine whether it is suitable for your
 purposes.
