Double precision words size which is 64 bit binary word size may not be sufficient to get results using many trigonometric calculations.
The non-precision of each calculation are accumulated. Rotate
a pattern which are some lines on the screen with some trigonometry. Then reverse the calculations to try to get back the orignal pattern. The original pattern or results is distorted a little. You can see the program on mywebsite: http://www.spots.ab.ca/~belfroy/computerPrecision.html .
This indicates that a computer hacker program may not always be powerful when using small binary word sizes when using many calculations on a few numbers for hacking.
