Noob: simpler way to generate random integers
Aug 20th, 2009, 10:05am  
Hi. I'm quite new to processing and I've been working a lot with random variables. The problem though is I only know one way to make them, and that is by generating a random float and then using int() to convert them. I haven't been able to find another way to do this, but surely there must be a more elegant way?

Code:
int r = int(random(99));


Isn't it elegant enough?

Or you can cast the returned value as an int:
Code:
int r = (int) random(99);


That's perhaps slightly nicer as it avoids putting two closing brackets together...  Not sure which is most efficient/quickest though.

Otherwise there are probably libraries that will do this, but I wouldn't bother with those unless they also provide additional functionality that you need...
