Our first converter!

You've probably used electronic converters or programs on many occasions to convert a quantity of one unit to a quantity of another unit. For example, dollars to pounds, or kilometers to miles. Now it's time for us to write such a tool. Specifically, we'll write a program that converts from degrees Celsius to degrees Fahrenheit.

(9.0 / 5) * celsius + 32 & (9 / 5.0) * celsius + 32 不然9/5是int类型

the decimal thing was strange, it reminds me of significant figures rules. the return issue was interesting bc it stuck out to me, but a few tries landed me with 'what should I tell it to return if this method is called' (not sure if that is the correct thinking, but it worked.) A little confused as to declaration of convertCelsiusToFahrenheit as it seems to do that within the creation of the composite type convertCelsiusToFahrenheit right after public static. the compiler didn't seem to like it if I didn't declare convertCelsiusToFahrenheit in the body. What is going on?...celcius seems fine as int..

In which lesson does it explain the variables double and return? Did I miss something? Im losing my mind!

I do not understand why the value assignation ignores "(9 / 5)" part. If I put 1.8 (the result of 9/5) It works fine!

Ich habe die richtige Antwort (105.8) aber trotzdem hatte ich Warnungen. Also sei vorsichtig die vierte Besonderheit. Benutzen sie das result command richtig.
