以太单位
一个整数的后面可以跟一个单位，ether，finney，szabo或者wei：
他们的单位换算如下：
- 1 ether = 1000 finney
- 1 ether = 1000000 szabo
- 1 ether = 10 ** 18 wei
pragma solidity ^0.4.14;
contract C {
uint a = 1 ether;
uint b = 10 ** 18 wei;
uint c = 1000 finney;
uint d = 1000000 szabo;
function isTrueAEquleToB() view public returns (bool) {
return a == b;
}
function isTrueAEquleToC() view public returns (bool) {
return a == c;
}
function isTrueAEquleToD() view public returns (bool) {
return a == d;
}
}
时间单位
时间的单位有seconds, minutes, hours, days, weeks 和 years。换算如下：
- 1 == 1 seconds
- 1 minutes == 60 seconds
- 1 hours == 60 minutes
- 1 days == 24 hours
- 1 weeks == 7 days
- 1 years == 365 days
pragma solidity ^0.4.4;
contract C {
// 1 == 1 seconds
// 1 minutes == 60 seconds
// 1 hours == 60 minutes
// 1 days == 24 hours
// 1 weeks == 7 days
// 1 years == 365 days
function test1() pure public returns (bool) {
return 1 == 1 seconds;
}
function test2() pure public returns (bool) {
return 1 minutes == 60 seconds;
}
function test3() pure public returns (bool) {
return 1 hours == 60 minutes;
}
function test4() pure public returns (bool) {
return 1 days == 24 hours;
}
function test5() pure public returns (bool) {
return 1 weeks == 7 days;
}
function test6() pure public returns (bool) {
return 1 years == 365 days;
}
}
