### round Rounds a number to a specified amount of digits. Use `Math.round()` and template literals to round the number to the specified number of digits. Omit the second argument, `decimals` to round to an integer. ```js const round = (n, decimals = 0) => Number(`${Math.round(`${n}e${decimals}`)}e-${decimals}`); ``` ```js round(1.005, 2); // 1.01 ```
