PRNG for a gaussian distribution?
You can generate any distribution by using a standard PRNG to choose&nbsp;$X$ uniformly from the interval $[0,1]$ and then returning $F^{-1}(X)$, where $F$ is the cumulative distribution function of the distribution you're interested in.

For the Gaussian distribution, though, it's usually better to use Box&ndash;Muller or ziggurat.
