## [BigFloats and BigInts](@id BigFloats-and-BigInts)

The [`BigFloat`](@ref) and [`BigInt`](@ref) types implements
arbitrary-precision floating point and integer arithmetic, respectively. For
[`BigFloat`](@ref) the [GNU MPFR library](https://www.mpfr.org/) is used,
and for [`BigInt`](@ref) the [GNU Multiple Precision Arithmetic Library (GMP)]
(https://gmplib.org) is used.
