Detailed Description

template<DGtal::Dimension dim>
struct DGtal::IntegerConverter< dim, DGtal::BigInteger >

Allows seamless conversion of integral types and lattice points, while checking for errors when going from a more precise to a less precise type.

Specialized version for BigInteger

Template Parameters

dim	static constant of type DGtal::Dimension that specifies the static dimension of the space and thus the number of elements of the Point or Vector.
