How does a random function works?

Question

I was thinking how does a library random function works .can anyone tell me how it works

Answer 1

Pseudorandom (predictable):
Takes a number from a seed (very long number), does math to it, returns it.
Other:
If you aren't looking too close, the amount of radiation is random. There is always a bit radiation. Take that number, do math to it and return it.
For more explanation: Try Google.

Answer 2

See my code here.. perhaps this could help you.. This is in Java..

Random rand = new Random();
int randomNum = rand.nextInt();

Here, randomNum is our any random number. You can try this on the code playground.
