I have tried to use doubles as you say or to use BitInt, but in both cases I have so far failed in producing working programs...

Regarding BigInt, once they are more complete and refined, they can become a built in of the language (they can be called "bint" for example). Multi-precision ints are useful, and this can improve their literals, their implicit conversions, etc.
