 The `rounding` argument may look like `{maximumFractionDigits: 10, roundingMode: "half-even"}` or `{maximumSignificantDigits: 10, roundingMode: "half-even"}`, where the roundingMode can be "floor", or "ceil", or "half-even", or "half-up".
 
+## Example:
+```javascript
+
+import BigDecimal from './node_modules/@yaffle/bigdecimal/BigDecimal.js';
+
+var pi = BigDecimal.multiply(BigDecimal.BigDecimal(4), BigDecimal.atan(BigDecimal.BigDecimal(1), {maximumSignificantDigits: 1000, roundingMode: 'half-even'}));
+
+console.log(pi.toString());
