Yes, 355÷113 is very close to π, but is not equal to π

So how does it get things 'right' for cos(355÷113), but not right for sin(355÷113)?

And why is the error of π-355÷113 exactly the same as the error of sin(355÷113)?

I sense some fuckiness of how they handle π...

Oh hell, alrighty then! Sure enough my old QBasic 3D graphics engine from 1998 was working in radians!

Holy hell I forgot about that, it's been about 27 years since I actually looked at my first rendering engine!

I'll see myself out now, but thank you for the refresher! 👍
