I was playing around with sin and cos but I noticed some of the values weren't accurate, in particular some of the main values.
Workaround: With the new update, just put everything in the "round" maths operator and it will make it zero for you. Not that it makes a difference because this is such a small problem anyway
Here are some pics-
sin 180 should be 0 and although this is very close, it's not quite 0.
sin 360 should be 0 also and the result looks like it has something to do with sin 180 being multiplied by -2.
When I look at all these actually, all these values I've picked up are meant to be 0.
Again cos 90 should be 0 though this is very close:
cos 270 should be 0 also.
It's not a huge issue like I said, you can just use the "round" operator if you want it to be exactly zero.
Please let me know if I'd made any mistakes too.
