How to create a random number between 0 and 1?
Hmmm.... may I suggest that you generate a counting number between 1 and 100 and then divide the resulting random integer by one hundred, casting to a float as needed, of course. This will give a fair approximation of a true random decimal between 0 and 1, I think.
Reply:Use the rand() func. Then divide by the value RAND_MAX.
