問題描述
MbUnit：比較雙打最優雅的方式？ (MbUnit: The most elegant way to compare doubles?)
The code
Assert.AreEqual (9.97320998018748d, observerPosition.CenterLongitude);
produces
Expected Value & Actual Value : 9.97320998018748
Remark : Both values look the same when formatted but they
are distinct instances.
What is the most elegant way to compare two doubles for equality in MbUnit 3.0? I know I could round them up myself, but is there some MbUnit construct for this?
UPDATE: I consider my current "workaround" to be non‑elegant:
Assert.LessThan(
Math.Abs(9.97320998018748d ‑ observerPosition.CenterLongitude),
0.0000001);
‑‑‑‑‑
參考解法
方法 1:
AreApproximatelyEqual seems to be the "MbUnit construct for this":
Verifies that an actual value approximately equals some expected value to within a specified delta.
This seems to be similar to Assert.AreEqual(double expected, double actual, double delta)
