Code Coach: How Many Miles?

Question

I’m doing the first code coach for Python 5.1. It asks:

Calculate and output the number of miles in 1000 kilometers.

Hint
One mile is 1.6 kilometers, so find the quotient of 1000 and 1.6.

I looked at my calculator beforehand and saw that 1000/1.6 is 625.0, no remainders, so why is it wrong when i do

print(1000/1.6)

and it displays 625.0, but right when i do

print(1000//1.6)

and it displays 624.0 when it’s mathematically wrong?

Answer 1

print(1000/1.6-1) # This answer also works, fooling the program asking to use "//" jaja

It seems that you are right, so curious...

Answer 2

Hi James Nguyen ,
Because integer / float is float
And because the result will be float, // rounds it down so 265.0 becomes 264.0

Answer 3

#your code goes here
x=1000
y=1.6
print (x//y)
