**demo.sol（货币单位）：**

pragma solidity ^0.4.0;
    
    contract EthUnit{
        uint  a = 1 ether;    // 货币单位。 数字与单位之间有空格。
        uint  b = 10 ** 18 wei;  // ** 表示次方
        uint  c = 1000 finney;
        uint  d = 1000000 szabo;
    
        function f1() constant public returns (bool){
            return a == b;  // true
        }
