## Usage

```javascript
const tau = require('math-tau');
```

Calculating the circumference of a circle
```javascript
const calculateCircumference = radius => tau * radius;
calculateCircumference(10); // 62.83185307179586
```

Euler's Formula
```javascript
const eulerFormula = i => Math.cos(tau) + i * Math.sin(tau);
eulerFormula(0); // Always (almost) 1
```

Extending native Math object
```javascript
Math.TAU = tau;
```

## Testing
Run `npm test` or testling to run the test suite.
