# Page 128 - Rounding numbers
In this section, I wrote about rounding rules as taught in schools and compare them to rounding rules when using C# and .NET. In schools, children are introduced to rounding rules with positive numbers and so learn the term "rounding up" and "rounding down". I did not explicitly say that for negative numbers, those terms would be reversed which can be confusing, so those terms should be avoided. This is why the .NET API uses the enum values `AwayFromZero`, `ToZero`, `ToEven`, `ToPositiveInfinity` and `ToNegativeInfinity` for improved clarity. In the next edition I will add a note about this.
# Page 153 - Writing a function that returns a value
At the end of this section there is a note box that explains that we could use the `C` format code to format the output as currency. If you are running on a computer in a culture that uses Euros then to show the Euro currency symbol you must enable UTF-8 encoding.
