Hi!
I don't get why this code doesn't work ( only test 1 and 2 are completed and others are hidden) , can i have some help please ?

Answer 1

A percentage value rounded up to the nearest whole number.
use Math.ceil() instead of Math.floor()
round up is done with ceil() not floor()

Answer 2

Thank you !
I misunderstood, i thought i had to round up to the nearest whole number, as the previous one if it was nearer than the next one.
