Question

contract MentalHealthCoin is ERC20, Ownable, ReentrancyGuard {
constructor() ERC20("Mental Health Coin", "MHC") {
_mint(msg.sender, 500000000(10**uint256(decimals()))); 
}

嗨，有人知道为什么会这样吗?

感谢我试着改变括号，但似乎没有工作。我现在在想这是否与薄荷功能有关

您忘记在500000000后面加上*了

contract MentalHealthCoin is ERC20, Ownable, ReentrancyGuard {
constructor() ERC20("Mental Health Coin", "MHC") {
_mint(msg.sender, 500000000*(10**uint256(decimals()))); 
}
}
