How do I find if two variables are approximately equals?

Question

I am writing unit tests that verify calculations in a database and there is a lot of rounding and truncating and stuff that mean that sometimes figures are slightly off.

Answer 1

The question was asking how to assert something was almost equal in unit testing. You assert something is almost equal by using the built-in Assert.AreEqual function. For example:

Assert.AreEqual(expected: 3.5, actual : 3.4999999, delta:0.1);

This test will pass. Problem solved and without having to write your own function!
