I could be wrong here so someone can correct me if they have a better understanding of why this happens. I think this has to do with the way a float is actually calculated using binary digits, it’s actually an equation that uses scientific notation to approximate a value. Because this equation uses 2 to a certain power, sometimes some exact values aren’t possible to calculate and you end up with a really really close approximation such as the numbers you’ve listed. I could be wrong, but I think the issue is with the data type (a float is only 32 bits, so only so many numbers are possible to be calculated), and it’s not an issue with the engine. I’d read into floating point numbers on Wikipedia or elsewhere if you want to learn more. Is this interfering with your work in any way or it just concerning you to see approximate values?
