Of particular importance is the solution of differential equations (symbolically or numerically; for ODEs or PDEs),
GiNaC does not provide such functionality. Have a look at - GNU octave (http://www.gnu.org/software/octave) - GNU scientific library (http://www.gnu.org/software/gsl) - PETCs library (http://www-unix.mcs.anl.gov/petsc/petsc-as)
so as variable precision arithmetic.
I'm just curious: why one would want to use bignums for solving ODEs (PDEs) numerically? I doubt Runge-Kutta (FEM) will ever give result with 53-bit accuracy, so storing even more mantissa bits is kind of pointless, isn't it? Best regards, Alexei -- All science is either physics or stamp collecting.
