To prevent errors arising in the calculations that occurred after the compilation of the contract, separate constants exFeePerTokenDenom, exFeePerTokenNum was replaced by Delta = (exFeePerTokenDenom - exFeePerTokenNum) and exFeePerTokenDenom:

Changes in the n2t SwapSell contract:

{1} -> MaxExFee[Long] {2} -> ExFeePerTokenDenom[Long]

{1} -> ExFeePerTokenDenom[Long] {2} -> Delta[Long]

All related calculations were updated to new logic.
