Hi @liurenjie1024 @Xuanwo @Fokko. Could you please review this PR and let me know if the fix makes sense? Thanks! |
Spec states that: "Decimal values are hashed using the minimum number of bytes required to hold the unscaled value as a two's complement big-endian". Prior to this fix, we would incorrectly consume leading 0xFF bytes and hash them. Now, we only consume the bytes starting with the one that is used to preserve the sign, and everything that follows that byte.
