Math-BigInt-BitVect Math::BigInt::BitVect is an alternative backend library for Math::BigInt::Calc. It can be used via: use Math::BigInt lib => 'BitVect'; If Bit::Vector is not installed, this will safely fall back to using the Math::BigInt::Calc backend library, the default library of Math::BigInt.
