Yes, Maxima can be used for calculations using arbitrary-size integers,
arbitrary-size rationals, machine floating-point, and arbitrary-precision
binary floating-points (bigfloats). Most numerically-oriented systems
handle only machine floating-point, and are optimized for it.
Sometimes I (in my opinion) it's hard to change fpprec in Maxima, see

Some parts of Maxima unfortunately don't know about bigfloats, in particular
the plotting routines. Sorry about that....
