How to set the ERC20 token price in respect to ether in solidity

Question

Hi, all

I have a input field in my DAPP where user can input ETH and click the submit button to get token worth ETH..How to calculate the token price in ether and get the token and show it in DAPP..

Token Price is 0.10 cents

function getPrice() public pure returns(uint256) {
     uint256 totalEther = uint256(225800608429140) / uint256(10**18);
     uint256 result = uint256(231481480000000) * 10**18;
     uint256 totalTokens = result / 1 ether;
    //  _totalEther =  totalEther;
     return totalTokens;
 }

but this isn't working.

Hi, @Jas,
In Solidity, you don't directly set a token's price in respect to Ether (ETH) within the ERC-20 contract itself. Instead, you typically create a mechanism (like a function) that defines the exchange rate between ETH and the token.
