in reply to Adding really big numbers

If you need to do that application wide, you can compile a custom perl that uses long doubles to represent floating point numbers.

x86 long doubles have 80 bits and a resolution of 18 digits. Other architectures as SPARC use 128 bits for long doubles.

Otherwise, you can use Math::LongDouble or Math::MPFR
