issue with yield

Question

I wrote his code:

def count():
i=10.4
while i>0:
yield i
i-=1
for i in count():
print(i)

the output I got was:

10.4
9.4
8.4
7.4
6.4
5.4
4.4
3.4000000000000004
2.4000000000000004
1.4000000000000004
0.40000000000000036

can someone explain why the difference between values changes to something else then 1.0 after a certain point?

I tried with different examples, like 8.7 or 14.3 and it's the same. it doesn't happen though if the float ends with 0 or 5, for example 6.5 or 20.0. neither does it happen when I write i+=I, only when it goes from bigger to smaller value.

Answer 1

Issue is not with yeild. It with floating point values.. It's because of compiler internal operations with float values..
