Sometimes,
we need to fix the precision
for our decimal numbers.
For example,
we might need 2.43519
to be represented as 2.44.
The toFixed() method fixes the number
of digits after the decimal point.
In the above example,
exactValue.toFixed(2) converts the value 4.34167
to have just 2 digits after the decimal point.
The toFixed method doesn't simply keep 2 digits after the decimal point
and
remove the rest,
it also rounds of the last digit.
In the above example,
instead of just returning a value with the first 2 decimal values,
i.e., "62.34",
we get the rounded value "62.35".
Note that toFixed() returns a string.
