What is the difference between this 2 code?

Question

This task is at functional programming -> lambda -> the task name: How much?

I needed to calculate the percentage of a given price and i wrote the first code that was wrong at test case #4, but the 2nd is correct.
The difference is at 《res=...》

price = int(input())
perc = int(input())
res = (lambda x,y: x/100*y) (price, perc)
print(res)

price = int(input())
perc = int(input())
res = (lambda x,y: x*y/100) (price, perc)
print(res)

Answer 1

It's a floating point precision issue.
