Python Problem with code

[camilin05]

Hi, I have a problem with this code:

x = int(input())

if x <= 100:
  y = 0.1
else:
  y = 0.25

precio = x * (1 - y)
print(precio)

The code seems fine to me, but I'm not expecting the answer that I wanted in the last testcase of the challenge that my teacher sent me. Here are the inputs and expected outputs:

58 = 52.2
7=6.3
200=150
199=149.3

When I display the code with the last input, the answer is 149.25, which is not what im looking for, what should I do?

My guess would be that the output is supposed to be rounded to 1 decimal place.

Can you post the program description, as stated in the exercise?

Based on the Python code you post here, there is no reason why Python should print 149.3 instead of 149.25. There must be something you're not telling us.
BTW Your statement I'm not expecting the answer that I wanted both amuses and confounds me. I guess you meant I'm not getting the answer that I expected ?

In this case precio simplifies to precio=199×0.75

• The number 199 is an integer, so it is represented exactly in memory.
• The number 0.75 (which is 3/4) is a finite binary fraction and can also be represented exactly in floating-point arithmetic.
• When multiplying 199 by 0.75, the result is exactly 149.25 as a floating-point value.
