Chapter 3: Problem 12

Assume that qty and salesReps are both integers. Use a type cast expression to rewrite the following statement so it will no longer perform integer division. unitsEach = qty / salesReps:

Short Answer

Expert verified
Answer: To avoid integer division, we can type cast either the numerator (qty) or the denominator (salesReps) to a float using the float() function. The modified statement would be: unitsEach = float(qty) / salesReps.

Step by step solution

01

Identify the issue with integer division

The given statement, unitsEach = qty / salesReps, performs integer division, which may not give the desired result, as it ignores any decimal values.
02

Use type casting to convert integers to float

To ensure that the division gives the correct decimal result, type cast either qty or salesReps, or both, into a float using the float() function: float(qty) or float(salesReps).
03

Rewrite the statement

After applying the type casting, rewrite the statement as follows: unitsEach = float(qty) / salesReps This will ensure that the division now gives the desired result with decimal values.
