I need your help about the solidity.
I need to set 1 token = 0.1$ in the presale and 1 token = 1.69$ in the Crowdsale.
But there is no float type on the smart contract.
How should I handle this?
I know one way to set 1 token = 100 and 1 token = 169 but this way is complex in the smart contract.
I need your good suggestions.
