How to stop/terminate a python script from running?
...
You can also do it if you use the exit() function in your code. More ideally, you can do sys.exit(). sys.exit() which might terminate Python even if you are running things in parallel through the multiprocessing package.
Note: In order to use the sys.exit(), you must import it: import sys

Which is the fastest algorithm to find prime numbers?
...
Actually I don't think primegen is the fastest, or even the second-fastest; yafu and primesieve are both faster in general, I think, and certainly over 2^32. Both are (modified) sieves of Eratosthenes rather than the Atkin-Berns...
Why doesn't C have unsigned floats?
... answer to that is that there was no unsigned float standard defined originally. Since languages like to be backwards compatible, even if it were added languages couldn't make use of it. To see the floating point spec you should look at the IEEE standard 754 Floating-Point.
