如何使用可接受的误差范围检查两位小数的相等性

Question

我有两位小数:

var first = 1.567m;
var second = 1.568m;
var areEqual = first == second; // false

我有一个可接受的误差范围; 是的0.010.
所以我需要的是一个Check方法:

Check(first: 1.567m, second: 1.577m, margin: 0.010m); // true
Check(first: 1.567m, second: 1.578m, margin: 0.010m); // false
Check(first: 1.567m, second: 1.578m, margin: 0.011m); // true

我该怎么写呢？

Answer 1

if (Math.Abs(first - second) <= margin)
