Question

I’m guessing that most built in random generators return something like this:

[0.0, 1.0) 

so if I would like a 50% chance would I use something like this:

if random() < .5 

or something like:

if random() <= .5 

Thanks for the help.

Answer 1

Ah, the old ‘.5’ problem. Here’s the answer:

If you’re going to divide 10 things into two equal parts, you need 5 things in each part. 0 thru 4 in the first part, 5-9 in the second part. So… < .5 is correct.
