Random number generation is a process by which, often by means of a random number generator, a sequence of numbers or symbols that cannot be reasonably predicted better than by random chance is generated.
There are generally two types of random number generators: pseudorandom number generators and true random number generators.
The randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs.
This version of the generator can create one or many random integers or decimals.
