BigFloat modules provide
variable-precision arithmetic and overloaded operators,
although they're currently pretty slow. At the cost of some
space and considerable speed, they avoid the normal pitfalls
associated with limited-precision
representations.

There are several modules that let you calculate with (bound only by memory and cpu-time) unlimited or fixed precision. There are also some non-standard modules that provide faster implementations via external C libraries.
