Well, whether it's simple depends on several things, e.g.:

    About what platform do you speak?
    Which compiler?
    How much is a _lot_ more?

For example, for some platform/compiler combinations, IEEE 32-bit floats are
the default Float type, while Long_Float is IEEE 64-bit.  Is 64-bit a _lot_
more than 32?

If you want something more than what is supported by the hardware, then it
certainly is no longer simple.  I don't know whether there are any arbitrary
precision Ada packages around.
