+Generates Gaussian (normally distributed) random numbers.
+
+- Use the [Box-Muller transform](https://en.wikipedia.org/wiki/Box%E2%80%93Muller_transform) to generate random numbers with a Gaussian distribution.
+
+```js
+const randomGauss = () => {
+  const theta = 2 * Math.PI * Math.random();
+  const rho = Math.sqrt(-2 * Math.log(1 - Math.random()));
+  return (rho * Math.cos(theta)) / 10.0 + 0.5;
+};
+```
+
+```js
+randomGauss(); // 0.5
+```
