Add EIP: EVM arbitrary precision decimal math #7904
Conversation
i know that the reference implementation is not abstract enough. it is running code, which should be clear. rather showcase the capability and if interest, write the tech specs for other clients.

(sorry, to the hackathon ppl, I don't why I forgot to add the main files to the assets. no sleep. adding now. had a link to the same.

| to this end, i have wrapped the underlying uint256 lib with gas accumulation, as found in the reference implementation in ../assets/eip-EVM+/uint256_wrapped.go. this gives a bottom-up approach to calculating gas, by running the OPCODE. |

| this gives an embedded gas calcuation, which works well for complex OPCODEs (see gasEVMPlusEmulate in ../assets/eip-EVM+/gasEVMPlusEmulate.go). | ||

| to remove the double gas, a future EIP would suggest the following: allow contract code to run whilst accumulating gas (at runtime) and panicking in case of limit breach, without requiring the cost in advance. this only works for contract code that is pure, defined as code that only depends on the user input and the inner bytecode of the contract. pure contracts cannot use state from the chain, nor make calls to other contracts. pure mathematical functions would e.g. be pure contracts. pure contracts are fully deterministic given the input, allowing a user to estimate gas costs offline (cheaper) and the EVM to panic at runtime, without knowing gas in advance. |

may be this section needs to be re-written in a "clearner" consistent way. TODO needs to be added as a todo markup

@g11tech, apologies for the delay in resolving your asks, was dealing with some health issues, good now, ty! |

@abcoathup @Pandapip1 @g11tech hi. i got the opportunity to present this EIP (and the corresponding win at EthOnline) on the Feb-23rd at EthDenver. do you think it might be possible to get this PR merged? thank you, it would be awesome for the talk. |
