function assertApproxEqAbs(uint256 a, uint256 b, uint256 maxDelta) internal virtual;
function assertApproxEqAbs(uint256 a, uint256 b, uint256 maxDelta, string memory err) internal virtual;
描述
断言 a
近似等于 b
,delta 为百分比
例子
function testFail () external {
uint256 a = 100;
uint256 b = 200;
assertApproxEqAbs(a, b, 90);
}
[PASS] testFail() (gas: 23169)
Logs:
Error: a ~= b not satisfied [uint]
Expected: 200
Actual: 100
Max Delta: 90
Delta: 100
