WebApr 7, 2024 · The same applies to floats (or, more accurately, it applies to Vector3 because it applies to floats). Floating point numbers are notoriously *slightly* inaccurate. The inaccuracies usually don't matter, UNLESS you're using the == operator, because 1.0000001 is not 1, and sometimes when using floats, 1f / 2f * 2f can equal 1.00000001.

WebJul 6, 2011 · If you go through a lot of floating point operations which in "infinite precision" might result in 0, you could end up with a result "very close" to 0. Typically in this situation you want to provide some sort of epsilon, and check that the result is just within that epsilon: if (Math.Abs (something) < 0.001) WebFloating point imprecision makes comparing floats using the equals operator inaccurate. For example, (1.0 == 10.0 / 10.0) might not return true every time.
