Ch. 2: less ambiguity about numbers #3895

chriskrycho · 2024-04-19T19:00:35Z

Applies @carols10cents’ suggestion on top of @victor-hernandez’s work in #3336 (I could not push to that branch or would have just done it there!).

Closes #3336.

The example code converts the input into a whole number. Replace the text "convert the String the program reads as input into a real number type" to "an actual number type" as the word real might be understood as one of the number categories instead as a synonym to "actual".
