Is there a library that will let me store big ints and then perform arithmetic on them in eos smart contracts? I was trying to use the multiprecision library in boost but kept on getting an error: https://github.com/EOSIO/eos/issues/4350

Performing arithmetic on the provided checksum256 type is not so easy as it is just an array of smaller ints.

  • How big of integers are you looking for? The smart contracts support uint128_t natively.

Yes, there's a big integer library for EOS.IO made by PlayerOne.

    this library is quite outdated. I had to make quite a few changes to get it to compile. Seems to be working so far though.
