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
|
|
```
