javascript provides the `tofixed()` method to round a number to a specified number of decimal places. here's a step-by-step tutorial on how to round a number to 2 decimals in javascript:
1. **create a number**: first, you need to have a number that you want to round to 2 decimal places. for example, let's say you have a number `num = 3.14159`.
2. **use `tofixed()` method**: you can use the `tofixed()` method on the number to round it to 2 decimal places. the `tofixed()` method returns a string representation of the number with the specified number of decimal places. in this case, you can use `num.tofixed(2)` to round `num` to 2 decimal places.
3. **convert back to a number (optional)**: if you need the rounded number as a numeric value instead of a string, you can use `parsefloat()` or the unary plus operator (`+`) to convert the string back to a number.
here's a code example demonstrating how to round a number to 2 decimal places in javascript:
in the example above, `num.tofixed(2)` rounds the number `3.14159` to 2 decimal places, resulting in the string `"3.14"`. you can then convert this string back to a number using `parsefloat()` if needed.
this is a simple and effective way to round a number to a specific number of decimal places in javascript using the `tofixed()` method.
