Hello,

You can either write your own BigNumber library to handle these big numbers
or use existing systems.

See

for one solution. This class require some other facilities from the boost
library (www.boost.org) as well.

lccwin32 has the qfloat type, it is able to let you use as much digits as
you want, as far as system resources allow you.

It's also free
