I was about to post this, so instead i'll second it. Theres no point in using more than 3-4 decimal points.isometry said:The other thing I don't understand is the purpose of using "30 to 50 digits." Even the most precise mouses have less than 100,000 dots per inch, and that's only 6 digits of precision. On the hardware level, 64-bit processors have 16 or so decimal digits of precision. With 20 digits of precision you could specify the distance an atom in New York and an atom in L.A. So I don't understand how 30 to 50 digits of precision can effect anything noticeable.
