**The type of the computed average**

Because the sum of the grades is maintained as type **double**,
the arithmetic will be performed as type **double** even though the number of
grades is an integer.

Thus, the output shown in Figure 2 would include a fractional part, such as 98.25 for example, if there is a fractional part.

(There was no fractional part in the average for the values illustrated in Figure 2.)
