Sometimes, we need to fix the precision
for our decimal numbers.
For example, we might need **2.43519**
to be represented as **2.44**,
which means we only want two digits
after the decimal point.
In such cases,
the method `toFixed()`

can help us.
It fixes the number of digits returned
after the decimal point.

To get the last digit in the result, it rounds the given number as shown in the example above.
