Then stores it in a 32bit integer losing precision, and then loads it back into float again - but this floating value is already rounded: "6263206400.0000000000". .NET uses a slightly different approach, so the rounded values do not match.

chickenbutt Posted October 20, 2015 Author Posted October 20, 2015 (edited) Inlining to put it in UI is a neat solution. The whole thing is based on equation x-((9.4837x)/100.0) even though this is just part of the key algo. It's the hardest part because of precision which is hundred thousandths before the last stage.
