func AmountIn
AmountIn is the ugnot/token that must be paid so AmountOut >= amountOut. Rounded up so ExactOut does not underpay.

func AmountOut
AmountOut is Uniswap-v2 getAmountOut against effective (real+virtual) reserves. Payout is capped by the real reserveOut — virtual offsets only affect price.
func MulDiv
MulDiv returns floor(a * b / d) for non-negative a, b and d > 0. Fast path uses int64 product. Overflow path is 128-bit (a*b)/d — same as int64((bigint(a)*bigint(b))/bigint(d)) — and panics only if the quotient does not fit int64. Gno has no typed bigint(int64) conversion.
func MulDivCeil
MulDivCeil is ceil(a * b / d) for non-negative a, b and d > 0. Ceil only when remainder != 0.
func Sqrt
Sqrt returns floor(sqrt(n)) for n >= 0 (Babylonian method).
