assertApproxEqAbs

Signature

function assertApproxEqAbs(uint256 left, uint256 right, uint256 maxDelta) internal;

function assertApproxEqAbs(uint256 left, uint256 right, uint256 maxDelta, string memory err) internal;

function assertApproxEqAbs(int256 left, int256 right, uint256 maxDelta) internal;

function assertApproxEqAbs(int256 left, int256 right, uint256 maxDelta, string memory err) internal;

Description

Asserts left is approximately equal to right with delta in absolute value.

Optionally includes an error message in the revert string.

Examples

function testRevert() external {
    uint256 a = 100;
    uint256 b = 200;

    assertApproxEqAbs(a, b, 90);
}

[FAIL: assertion failed: 100 !~= 200 (max delta: 90, real delta: 100)] testRevert() (gas: 23884)
