Why do I see a double variable initialized to some value like 21.4 as 21.399999618530273?
If you have a value like: double theta = 21.4; And you want to do: if (theta == 21.4) { } You have to be a bit clever, you will need to check if the value of theta is really close to 21.4, but not necessarily that value. if (fabs(theta – 21.4) <= 1e-6) { … Read more
