In which order should floats be added to get the most precise result?
...s things somewhat. Consider the case where we're adding single-precision (32 bit) floats, and there are 1 billion values equal to 1 / (1 billion), and one value equal to 1. If the 1 comes first, then the sum will come to 1, since 1 + (1 / 1 billion) is 1 due to loss of precision. Each addition has n...
Why do == comparisons with Integer.valueOf(String) give different results for 127 and 128?
...is returning an Integer object, which may have its values cached between -128 and 127. This is why the first value returns true - it's cached - and the second value returns false - 128 isn't a cached value, so you're getting two separate Integer instances.
It is important to note that you are comp...

...s, if the input IS a string? You can use one of these:
string.Format("{0:G29}", decimal.Parse("2.0044"))
decimal.Parse("2.0044").ToString("G29")
2.0m.ToString("G29")
This should work for all input.

What's the difference between Unicode and UTF-8? [duplicate]
... was all devised in the early days of Unicode, before we realised that UCS-2 wasn't enough, and before UTF-8 was invented. This is why Windows's support for UTF-8 is all-round poor.
