start = 0.65
end = 0.75
step = 0.01
while start <= end:
print (start)
start += step
But why am I getting below? really
0.65
0.66
0.67
0.68
0.6900000000000001
0.7000000000000001
0.7100000000000001
0.7200000000000001
0.7300000000000001
0.7400000000000001
where did 0.0000000000000001 come from?
thanks a lot!
This questioned has been answered before here. In summary, it has to do with how values are stored, so 0.1 is actually stored as exactly 0.1000000000000000055511151231257827021181583404541015625 hence why you get the extra 1 at the end. You can look more into by clicking on the link. To solve this problem, you can use the built-in round function. Like so:
start = 0.65
end = 0.75
step = 0.01
while start <= end:
print (start)
start = round(start + step, 2) # this rounds the answer to the nearest hundredth
Hope this helped!
