Is Ann correct?

Line 102 in 8c338d1

Ann: uint256 = convert(self.A, uint256) * N_COINS

should be:
Ann: uint256 = convert(self.A, uint256) * N_COINS * N_COINS

I think it should be changed
convert(self.A, uint256) * (N_COINS ** N_COINS)
not
convert(self.A, uint256) * N_COINS * N_COINS

I think this question can be solved by this annotation.

The A passed into the contract is "A * (n ** (n - 1))" (there is a typo on it.), not the A shown in the equation. Thus, Ann is correct. Maybe the "self.A" might not be named as "self.A", it will make people confused.
