Performance was not the primary motivation. I found it confusing to have doubles everywhere and not to know whether a variable is declared as double, because . we need the fractional part (e.g. a probability) . or it should be able to hold an integral value of more than 32 bits. So I just invented my own datatype for huge integers. Long long would have been a natural choice, but AFAIK its not available on all platforms. >I was initially convinced that your implementation of Knuth's algorithm >S was all wet, so now there's a bunch of comments explaining why it's >actually correct... Thanks. I like your explanation. My justification for that change was a lot more complicated.
