# Yellow Paper Appendix H - https://ethereum.github.io/yellowpaper/paper.pdf
|
||
# Special notes from Yellow Paper:
|
||
# - Signed values are treated as two’s complement signed 256-bit integers.
|
||
# - When −2^255 is negated, there is an overflow
|
||
# - For addmod and mulmod, intermediate computations are not subject to the 2^256 modulo.
|
||
# Nimbus authors note:
|
||
# - This means that we can't naively do (UInt256 + UInt256) mod uint256,
|
||
# because the intermediate sum (or multiplication) might roll over if
|
||
# intermediate result is greater or equal 2^256
