If you enter a limit of 1000.0, what would be printed out if the arithmetic were perfectly accurate?

A good answer might be:

1000.0. The variable starts out at 0.0, and would have 0.1 added to it until it became 999.9. This last value would pass the while's condition, and would have 0.1 added to it to become 1000.0, which would not be < limit.

I hope you were not counting on more lessons, because this is the end of the chapter. You may wish to review the following.
