Python Basics: Numbers and Math (Quiz)

Easy!

Seriously the whole course had like 5 quiz questions and nothing else ? After the 4th course of RealPython I’m getting really disappointed.

@Janos Antal There is also a practical part: Python Basics Exercises: Numbers and Math

Hello, I found this course interesting. I heard the float type was not very precise but your demontration of 0.1+0.2 convinced me. I did not quite understand the use of decimals in practical terms as an alternative to float, that’s the only thing i missed here.

The quiz explains // as “Integer or floor division, divides the left operand by the right operand then rounds the result to the nearest whole number”, but like in the ‘Arithmetic Operators and Expressions’ module, this is incorrect. It should say “rounds the result down to the nearest whole number”. I added a comment in that module, but briefly:

>>> 99/100
0.99
>>> 99//100
0
