# Random Numbers

## Generating Pseudo-Random Numbers in Scheme

Recently, I needed to write a simple simulation in multiple programming languages. For the simulations to operate, they needed a source of random numbers from two statistical distributions: a uniform distribution and a standard distribution. The numbers from the distributions needed to be “random”, but not too random. I needed each generator in each language to produce the same sequence of “pseudo-random” numbers. And I needed the same sequence every time the simulators were run.
