The goal for this exercise is to extend what was done in the first lesson, adding some more detail to how math is done in C#
What you need to do to prepare for this exercise:
Prior to this exercise, you should read about the two types of division in C# (and most other programming languages) – integer division, and the normal, floating-point division.
Download the starter project for the PCEs (if you haven’t already), and add code to the Integer_Vs_Real_Division.
RunExercise() method that prints out the result of doing integer division where
the result is exact (i.e., 6/3)
the result will drop the remainder (i.e., 7/3)
Next, do the same divisions using floating-point division, and print out those results. Do this using both a float and then again using double.
Include a short comment explaining why your code doesn’t always generate an exact answer (e.g., why does 7/3 not produce a number like 2.3333, but 7.0/3.0 does?). Focus your answer on explaining why (syntactically) C# decides to give you the rounded-off answer.
Include a short comment explaining why using the float doesn’t get you exactly the same answer as using the double data type.
Note For Studying:
Please keep in mind that many of the C# language topics we'll be looking at tend to have a lot less stuff to memorize, but each item can be used in lots of different places – use this to optimize your study strategies for the C# language!
