remove zeros at the end of a number

[Frankduc]

Book is dated 2020. I check on stackoverflow and other sites but info are sometimes contradictory. I use the forum as another source of info. But i am not disappointed, people are nice here, give good and fast info. Maybe not perfect but most of the time reliable. I wouldn't say impose but everytime i use import math or any other module it put automatically a * next to it. I can delete it, true, but its coming back.
